How many months are there between two dates? Calculate days, months and years between two dates online
Apparently this is a very common occurrence. I immediately went online to search online service, which 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

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 days off, specified in a certain form (this function is not displayed on the site, although the functionality is working) and for everyone, building a production calendar for Belarus, Kazakhstan or Serbia will not be difficult.
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.
For users who need to calculate the first working date after a vacation or business trip or other period of time, pay attention to this calculator. Date of return to work from vacation, maternity leave online

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 days between two specified dates 1212
Number of working days 827
Number of weekends and holidays 385
rab_d 20/1/2010;10/2/2014;0101001

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 now let's look at this issue 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, one. 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 in the list the desired function. Click "OK".
Next you need to select the function arguments. In “Start_date” we select the initial value (A6), in “End_date” we select the final value (B6). In the last field, enter the dates of holidays in parentheses () 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 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.
| Beginning of the period (either through a slash or a dot) |
| End of period (either through a slash or dot) |
| Marked weekends in the week |
