In the amount of 7 days. Days between dates calculator

A calculator of days between two dates can be useful for an accountant or HR manager. This calculation tool will also help a lawyer when, in order to file a lawsuit, he needs to find out the number of days the payment is overdue.

  • how many calendar days have passed between two given dates;
  • how many working days and hours are there in the period you specify;
  • how many days off there were in the period you specified.

How to use the days between two dates calculator

You only need two values. In the appropriate fields of the calculator you need to indicate the start and end dates of the period - day, month and year. Simply click on the desired cell with the left mouse button and select the desired option from the list.

You should also set the number of working hours per day. For example, for office workers the standard working day is 8 hours, but in production a work shift can last 10 hours. By default, the calculator indicates 8 working hours per day.

After you enter the required values ​​into the fields of the calculator, the full calculation will be displayed on the right. In it you will see the number of calendar and working days, as well as the number of working hours according to the specified parameters.

Example. The director of Mechta LLC gave instructions to the chief accountant to calculate the number of hours worked in the fourth quarter of 2018. During this period, all employees of the company worked according to schedule and did not go on vacation. The chief accountant opened an online calculator and entered the following data:

Starting date: 10/01/2018

End date: 12/31/2018

The chief accountant left the “Number of working hours” field unchanged.

The calculator automatically performed the calculation and produced the following numbers:

  • calendar days - 92;
  • working days - 65;
  • working hours - 520.

Time calculations are constantly encountered in everyday life: from calculating days until a significant date to calculating the time of vacation or the period of payment on a bank loan. A collection of online calculators will help you easily operate such a complex parameter as time.

Time

Time management is not the name of a magic spell from a computer game, but a very real ability that has gained enormous popularity among businessmen and investors. Time management or is a technique for calculating time periods to effectively complete a certain amount of work. Thanks to competent and rest periods, people who use money management techniques manage to do much more than those who do not keep track of time and suffer from.

Naturally, time management is the science of more than just time distribution. The most important skills that allow you to competently organize work include:

  • and manage resources;
  • prioritize and;
  • allocate time and analyze results.

Delegation is the transfer of work to subordinates or colleagues. Many ineffective managers believe that no one can do better than themselves. Naturally, overwhelmed with a bunch of unimportant work, they do not have time to complete priority tasks, as a result of which they become ineffective.

Finding priorities is an equally important thing. states that 80% of the result comes from 20% of the effort. In practice, this means that it is important to complete only those tasks on time on which 80% of success depends. As a rule, there are few such tasks, not strictly 20% as the Pareto principle promises, but usually in the range from 20 to 40%. It is the ability to separate the wheat from the chaff that creates productive leaders and businessmen.

The most famous, effective and at the same time the simplest technique is considered to be “Pomodoro”. This is a time management technique, according to which work is performed at strictly designated intervals (usually 20 minutes), each of which is accompanied by a five-minute rest. The Pomodoro technique got its name because its creator measured periods of time using a kitchen timer in the shape of a tomato. Since then, modernized versions of time management have formed the basis for the success of prominent business representatives.

Timing

You can use the principles of money management not only when solving daily problems, but also when planning large projects that take weeks or months to complete. First of all, you should find out by what deadline the project must be completed or how much time is allocated for it. Let's take a closer look.

Number of days between two dates

This tool allows you to determine the number of days between two dates. For example, on October 20, 2017, you were assigned a project that must be completed by January 18, 2018. Going to the calendar and counting the time is not very convenient and it’s easier to use a calculator: just select the type of program and enter both dates. In the answer we see that you have 2 months and 29 days to complete the plan. Not very informative when planning. The program also expresses this time in days, weeks or months. Let's see. You have exactly 90 days or 12 working weeks. With this, you can already build an effective time management system and avoid deadlines.

What date will be in n days

Another convenient tool for efficient work. A large project at work may be assigned with the note “to be completed within 50 days after acceptance of the order.” This is a large amount of time, but again running to the calendar and calculating it is not very convenient. We use a calculator. Let's say the order was accepted for work on April 28, 2017. By what day does it need to be delivered to the customer? Let's change the calculator type and calculate the deadline date. It will be June 17, 2017, Saturday. Having the total number of days and the X date at hand, you can easily distribute efforts to complete the work on time.

What date was n days ago

This calculator will not be useful to you at work, but it will certainly come to the rescue in your personal life. Imagine that you received an SMS message in which your crush congratulates you on your 100th day of marriage. This is an important date that should not be forgotten, so it is better to use the program and find out about it. You received an SMS on July 4, 2017, now it’s easy to find out when you moved in with your crush. So, select the type of calculator, enter the date and the anniversary 100 days. Your memorable date is March 26, 2017, Sunday. It's worth circling this date on your calendar.

Temporary quantities

This calculator allows you to convert one time value into another. Using the program, you can express minutes into days, weeks into years, or centuries into millennia. In practice, this can be useful when calculating working hours for freelancers and freelance artists. For example, you have 28 working days to complete your next order. This is 672 hours. Let's take away the time for sleep 28 × 8 = 224, the time for breaks and rest 28 × 4 = 112 and we get that you have 336 hours for effective work. You can already work with this and use time management techniques for productive work.

Amount/time difference

This program gives you the ability to add hours or days and calculate the total time in months, weeks, days, minutes, seconds and even milliseconds. This is a fun calculator that can be used in practice to calculate the time required to complete several types of work or to calculate the free time remaining after completing a task.

Apparently this is a very common occurrence. I immediately went online to look for an online service that allows calculate how old a person is by his date of birth.

As expected, such services exist. And not a little. Talented PHP programmers took care of "lost in time" and wrote all sorts of calculator scripts for counting years by date of birth, or simply calculating the number of years, months, days, hours, minutes and even seconds between two dates online.

I want to write about some of them.

Calculation of how many years, months, days, hours, minutes have passed by date of birth

Surely many have asked the question: “How many days do I live?” . But not many bothered to count. This is a very tedious task. But using this site:

you can easily calculate by date of birth. You will find out how old you are, months, days, hours, minutes, seconds and even milliseconds.

The service will also tell you when your next birthday will be.

Calculate days and years between two dates - online calculator

http://planetcalc.ru/274/ - with the help of this calculator you will be able to count days and years between two dates in online mode. Just enter the required data and the service will give you the exact result.

Counting the number of days from a date to a date

http://www.calculator888.ru/skolko-dnei/ is another site where you can find out exactly how old a person is. Moreover, it can calculate online the number of years, months, days, hours, minutes, seconds that have passed from one date to another.

To calculate age or length of service we will use an undocumented Excel function - RAZNDAT()(in the English version of Excel - DATEDIF())

The description of this function is only in the English help, it cannot be called in the standard way, it is saved in Excel only for compatibility with older versions of Excel and Lotus 1-2-3

But despite this, if we write it in Excel, then it will work perfectly in all versions of Excel without the need to enable or install anything additional.

Function Syntax RAZNDAT()with the help of which we will calculate the age or length of service of a person as follows:

=DATE(start_date, end_date, measurement_method)

start_date- this is the reference date, if we calculate age, then this is the date of birth, if we calculate work experience, then this is the date of employment.

final date- this is the date for which we need to calculate this or that value. If we consider length of service and age, then, as a rule, we need to calculate for today's date. That is, how much length of service does the employee have from the beginning of the date of employment until today. The same is true for the date of birth. The current date can be inserted manually, but if you open the file the next day, today's date will turn into yesterday's, so you can use the function TODAY() , which will automatically insert today's date whenever the file is updated. So you have work experience or age will be calculated automatically in Excel whenever you open a file.

Particular attention should be paid to the very last argument - measurement_method , which defines the type and unit of measurement between the start and end dates. All possible variations of this argument are listed below:

  • "y" date difference in full years
  • "m" date difference in full months
  • "d" date difference in full days
  • "yd" date difference in days from the beginning of the year, excluding years
  • "md" date difference in days excluding months and years
  • "ym" date difference in full months excluding years

RAZNDAT(A2 ;B2 ;“y”)

In the English version of Excel =DATEDIF(A2;B2; “y”)

Or you can delete the second column and write the formula = RAZNDAT(A2 ;Today() ;“y”)

The most important thing is that date and month of birth will be taken into account, for example, if today was 04/10/2014 (in the example in the picture), then the age would not be 31, but 30 years old, since the birthday in 2014 has not yet arrived.

If you want to indicate your work experience in full, for example “2 years 3 months. 4 days", then the formula will look like this:

RAZNDAT(A2 ;B2 ;“y” )& " g. "&RAZNDAT(A2 ;B2 ;“ym" )& " month "&RAZNDAT(A2 ;B2 ;“md" )& " days "

in English version of Excel =DATEDIF (A2;B2; “y”)& “year”&DATEDIF (A2;B2; “ym”)& “mo. "&DATEDIF (A2;B2; "md")& "day"

Here we first calculate the number of full years “y”, then the number of full months excluding years “ym” and the last one is "md" — date difference excluding months and years. After that, all these and we get the result we need.

To perform certain tasks in Excel, you need to determine how many days have passed between certain dates. Fortunately, the program has tools that can solve this issue. Let's find out how you can calculate the date difference in Excel.

Before you start working with dates, you need to format the cells to fit this format. In most cases, when you enter a set of characters similar to a date, the cell itself is reformatted. But it’s better to do it manually to protect yourself from surprises.


Now the program will recognize all the data that will be contained in the selected cells as a date.

Method 1: simple calculation

The easiest way to calculate the difference in days between dates is to use the usual formula.


Method 2: RAZNDAT function

You can also use a special function to calculate the difference in dates RAZNDAT. The problem is that it is not in the Function Wizard list, so you will have to enter the formula manually. Its syntax looks like this:

RAZNDAT(start_date, end_date, unit)

"Unit"— this is the format in which the result will be displayed in the selected cell. The units in which the total will be returned depends on which character is inserted into this parameter:

  • "y" - full years;
  • "m" - full months;
  • "d" - days;
  • "YM" - difference in months;
  • “MD” is the difference in days (months and years are not taken into account);
  • “YD” is the difference in days (years are not taken into account).

You should also note that, unlike the simple formula method described above, when using this function, the start date should be in the first place, and the end date in the second. Otherwise, the calculations will be incorrect.


Method 3: Calculating the number of working days

In Excel it is also possible to calculate working days between two dates, that is, excluding weekends and holidays. To do this, use the function CHISTRABNI. Unlike the previous operator, it is present in the Function Wizard list. The syntax for this function is as follows:

NETWORKDAYS(start_date, end_date, [holidays])

In this function the main arguments are the same as those of the operator RAZNDAT– start and end date. There is also an optional argument "Holidays".

Instead, you should substitute the dates of non-working holidays, if any, for the period covered. The function calculates all days of the specified range, excluding Saturdays, Sundays, as well as those days added by the user to the argument "Holidays".


After the above manipulations, the number of working days for the specified period will be displayed in the previously selected cell.

As you can see, Excel provides its users with quite convenient tools for calculating the number of days between two dates. At the same time, if you just need to calculate the difference in days, then the best option would be to use a simple subtraction formula rather than using the function RAZNDAT. But if you need, for example, to count the number of working days, then the function will come to the rescue NETWORKDAYS. That is, as always, the user should decide on the execution tool after he has set a specific task.
