Calculate the number of days between dates. Calculating date difference in Microsoft Excel

The date calculator is designed to calculate the number of days between dates, as well as to find a date by adding or subtracting a certain number of days to a known date.

Add days to date

In order to find out what date will be in a certain number of days, use this option. Enter the starting date and the number of days to add to it. To subtract, use a minus value. The calculator also has an option to add only working days.

Calculating the number of days between dates

This calculation method will answer the question "how many days have passed since the date". Enter the start date and end date and click the "calculate" button. The calculator will show how many days there are between the entered dates. Separately, the calculator will show the number of working days.

Using this option, you can calculate how many days are left until a certain event, for example, a birthday or holiday. To do this, enter today's date in the start date field, and the event date in the end date field.

Holidays

The calculator can calculate, add and subtract as calendar days, and workers. Official non-working days holidays are:

January 1,2,3,4,5,6,8 - New Year holidays
January 7 - Orthodox Christmas
February 23 - Defender of the Fatherland Day
March 8 - International Women's Day
May 1 - Spring and Labor Day
May 9 - Victory Day
June 12 - Russia Day
November 4 - National Unity Day

If a holiday falls on a Saturday or Sunday, it is moved to the next working day. But sometimes the weekend is moved to a completely different place on the calendar. For example, Saturday and Sunday that fall on the New Year holidays may be moved to May in order to extend the May holidays.

So, in 2019 the situation is as follows...

Postponement of holidays in 2019

In addition to the official holiday dates, in 2019 the weekends are also May 2, 3 and 10 due to the postponement of the weekend from the New Year holidays.

When calculating days, our calculator takes into account both official holiday dates and all transfers.

Calculation of working days and weekends

The calculator is quite simple, but nevertheless, in my opinion, very convenient for calculating the number of working days between arbitrary dates.

The calculator uses data on the transfer of working days and holidays, which are contained in the annual decrees of the Government of the Russian Federation.

Of course, there are many such calculators and we are not original in this, but there are several highlights that I think you will like and can be used to create other calculators.

First highlight: We may not take into account holiday dates contained in the decrees of the Government of the Russian Federation, but only take into account weekends (for Russia, Saturday and Sunday)

The second highlight: For those countries whose days off are other days of the week (for example, in Israel, the days off are Friday and Saturday), you can specify which days of the week will be days off. This is convenient not only for other countries, but also for local use, when it is known that we work in shifts every Thursday, Saturday and Tuesday.

Third highlight: We can use a completely arbitrary system of holidays, specified in a certain form (this function is not displayed on the site, although the functionality is working) and for everyone to build production calendar for Belarus, Kazakhstan or Serbia there will be no difficulty.

A pleasant side effect of this calculator is also the calculation of the number of days between two dates. Moreover, she calculates the difference in the same way as it is done in the accounting and personnel departments. That is, if a person works from July 1 to July 8, then it turns out to be 8 days. Since the last day is considered a working day.

Unlike mathematical and astronomical calculators, where with the same data it turns out to be 7 days. This error in one day appears due to the fact that in personnel decisions the last day is always a working day and must be taken into account, and in precise and abstract calculators it is believed that July 8 comes at midnight (0:0:0) and the difference between midnight on July 1 and midnight on July 8 (or 23 hours 59 minutes 59 seconds 999 milliseconds, 999999 microseconds, etc. on July 7) will be exactly 7 days.

The main principle that the bot adheres to is the frequency of days off during the week. If this is observed, the calculator will give the result you expected.

It is a pity that the resolutions of the Government of the Russian Federation still do not implement a QR code, where all holidays for the current code would be indicated for machine processing. This would simplify the work of a certain circle of people.

Holidays and transfers on the territory of the Russian Federation are taken into account from 2010 to 2019 inclusive.

rab_d date.start; end date;week

a week - gives full information about how to calculate working days and hours. A week consists of seven symbols 0 or 1, where each symbol has its own role. 0 - person is working, 1 - person is not working (day off). If the week is empty, then the code 0000011 is used - that is, Saturday and Sunday are closed.

I would like to note that this is a calendar week and this indicator shows how you rest during the week. Our week numbering starts from zero and this day is Monday, then Tuesday -1, Wednesday -2, etc.

start date - date in the form DD/MM/YYYY - indicates the beginning of the range for which the number of working days is calculated

end date - date in the form DD/MM/YYYY - indicates the end of the range for which the number of working days is calculated

ATTENTION! The date can be entered using a period or a slash. It is more convenient to enter through a dot on cell phones and tablets, and through a slash it is more convenient to enter on a computer on the keyboard on the right (digital panel)

Examples of using

rab_d 1/1/2014;31/12/2014

in response we will receive

Number of days between two specified dates 365

Number of working days 247

Number of days off and holidays 118

rab_d 2/7/2010;25/10/2013

In response we will receive

Number of working days 827

Number of weekends and holidays 385

rab_d 20/1/2010;10/2/2014;0101001

In response we get

Number of days between two specified dates 1483

Number of working days 797

Previous example, just ignore public holidays. As an option for use, shift duty, security, etc.

Free online calculator Contour.Accounting will help you and tell you how many days have passed between two given dates. In addition, if you have a need, you can count how many calendar, weekends or working days (hours) a specified period of a year or several years contains.

How many days are there between dates? Instructions

You simply set a specific start and end day and get a quote in a split second. The online calculator calculates all data independently. If you change the original days of the week, the result is automatically recalculated to take into account leap years.

Important: you cannot take monthly working days/hours from last year’s calculations and provide them as calculations - the data will vary. Therefore, it is better to use a calculator.

So, the procedure is:

In the “Start date” and “End date” fields, select the start and end day of the countdown, respectively, starting from 2013 and ending in the future in 2018.
Set the number of working hours in a day in the next field. By default, this field is already set to 8 hours (40 hour work week), but you can change this number.
On the right side of the screen in the banner you will see the result: working days, calendar days and working hours between the specified dates. The results must be copied and saved in your document.

What can you use a calculator for?

To calculate penalties and delays under contracts
How to understand the efficiency of using a resource and the deadlines for use
How to avoid accidentally scheduling tasks on a weekend
How much time is left until the deadline

Example:

You are an accountant. The manager has asked you, in the next couple of minutes, to provide data on the number of working hours that all company employees must work in February. You can easily determine the number of employees - you have the numbers in front of your eyes. But the number of hours needs to be counted.... How many days are there in February? Is it a leap year? What days were weekends? How to determine the number of days of holidays?

Solution: just use our widget. You will receive all the information automatically; you do not need desktop calendars and calculators.

If on an Excel sheet you work not only with numbers, graphs, pictures, but also with dates, then you have probably encountered a situation where you needed to calculate the difference between them. For example, you need to determine the number of days or months for a certain period of time, or calculate the age of a person so that the result is in days, months and years, or maybe you need to calculate exactly working days.

There is already an article about calculating the difference in Excel on the site, and in it I touched on dates a little. But for now let's look this question in more detail and figure out how to calculate the number of days between two dates in a simple way or using the RAZNDAT() function, and how to determine the number of working days.

Method 1: Subtraction

Let's start with the simplest thing - subtract the second from one date, and get the value we need. Before doing this, make sure that the format of the cells in which the numbers are written is “Date”.

If you haven’t filled them in yet, then select the range you want to work with and click on the small arrow next to the name of the “Number” group.

In the window that opens on the left, select the format that suits us, and then in the main area, decide on the type: 03/14/12, 14 Mar 12 or another. Click "OK".

In those cells for which you just changed the format, enter data. I filled out A1 and B1. Now you need to select any cell (D1) in which the general data format is set, otherwise the calculations will be incorrect. Put “=” in it and press first the late (B1) date, then the early (A1). To calculate the number of days between them, press “Enter”.

Method 2: Using a function

To do this, select the cell in which the result will be (B3), and make sure that the general format is selected for it.

To calculate days we will use the AZNDAT() function. It includes three arguments: start and end date, unit. Unit is what we want to get the result in. Substituted here:

“d” – number of days;
“m” – number of full months;
“y” – number of full years;
“md” – will count days without taking into account months and years;
“yd” – counting days without taking into account only years;
“ym” – will count the months without taking into account the year.

We put an equal sign in B3, write RAZNDAT and open the bracket. Then select the early date (A1), then the latest date (B1), put a suitable unit in quotes and close the bracket. Place ";" between all arguments. . To calculate, press "Enter".

I came up with this formula:

RAZNDAT(A1;B1;"d")

Choosing “d” as the unit, I got the result - 111.

If you change given value, for example, on “md”, then the formula will calculate the difference between 5 and 24 without taking into account months and years.

By changing this argument in this way, it will be possible to derive the exact age of the person. In one cell there will be years “y”, the second month “ym”, the third day “md”

Method 3: counting working days

For example, let's take this sign. In column A we have the beginning of the month or the starting date of the countdown, in B we have the end of the month or countdown. This function counts working days without taking into account Saturday and Sunday, but there are also holidays in the months, so we will fill column C with the corresponding dates.

NETWORKDAYS(A5;B5;C5)

As arguments we indicate the start date (A5), then the end date (B5). The last argument is holidays (C5). We separate them with ";" .

By pressing “Enter” the result will appear, in the example cell D5 – 21 days.

Now consider if there are several holidays in a month. For example, in January New Year and Christmas. Select cell (D6) and put equal in it. Then click on the letter “f” in the formula bar. A window will open "Insert a function". In the Category field, select "Complete alphabetical list" and find the function you need in the list. Click "OK".

Next you need to select the function arguments. In “Start_date” select the initial value (A6), in “End_date” select the final value (B6). In the last field, enter the dates of holidays in brackets () and quotation marks "". Then click "OK".

As a result, we will get the following function and the value will be calculated without taking into account weekends and specified holidays:

NETWORKDAYS(A6;B6;("01/01/17";"01/07/17"))

To avoid entering holidays manually, you can specify a specific range in the corresponding field. Mine is C6:C7.

The working days will be counted, and the function will look like:

NETWORKDAYS(A6;B6;C6:C7)

Now let's do the calculations for the last month. Enter the function and fill in its arguments:

NETWORKDAYS(A8;B8;C8)

In February there were 19 working days.

I wrote a separate article about other date and time functions in Excel, and you can read it by following the link.
