Excel has some powerful functions to calculate the number of days between two dates in Excel. These are especially useful when you’re creating Gantt charts or timelines for a proposal/project.

In this tutorial, you’ll learn how to calculate the number of:

- Days between two dates.
- Working days between two dates.
- Weekends between two dates.
- Working Days in a part-time job.
- Specific Days (such as Mondays or Tuesdays) between two dates.

## Calculating the Total Number of Days Between Two Dates in Excel

Excel Days function can be used to calculate the total number of days between two dates in Excel.

You need to specify the ‘Start Date’ and the ‘End Date’ in the Days function, and it will give you the total number of days between the two specified dates.

For example, suppose you have the start date is in cell B1 and End Date is in cell B2 (as shown below):

The following formula will give you the total number of days between the two dates:

=DAYS(B2,B1)

Note that you can also manually specify the dates in the Days function by putting it in double quotes. Just make sure these dates in double quotes is in an accepted date format in Excel.

## Calculating the Total Number of Working Days Between Two Dates in Excel

Excel has two functions that will give you the total number of working days between two dates and will automatically account for weekends and specified holidays.

- Excel NETWORKDAYS function – you should use this when the weekend days are Saturday and Sunday.
- Excel NETWORKDAYS INTERNATIONAL function – use this when the weekend days are not Saturday and Sunday.

Let’s first quickly have a look at NETWORKDAYS Function syntax and arguments.

**Excel NETWORKDAYS Function – Syntax & Arguments**

=NETWORKDAYS(start_date, end_date, [holidays])

- start_date – a date value that represents the start date.
- end_date – a date value that represents the end date.
- [holidays] – (Optional) It is a range of dates that are excluded from the calculation. For example, these could be national/public holidays. This could be entered as a reference to a range of cells that contains the dates, an array of serial numbers that represent the dates, or a named range.

Let’s first look at an example where you want to calculate the number of working days (business days) between two dates with Saturday and Sunday as weekends.

To calculate the number of working days (Column D) – when the start date, end date, and holidays are specified – use the below formula in D3 and copy for all cells:

=NETWORKDAYS(B2,C2,$F$2:$F$6)

This function works great in most cases, except the ones where the weekends are days other than Saturday and Sunday.

For example, in middle-eastern countries, the weekend is Friday and Saturday, or in some jobs, people may have a six-day workweek.

To tackle such cases, Excel has another function – NETWORKDAYS.INTL (introduced in Excel 2010).

Before I take you through the example, let’s quickly learn about the syntax and arguments of Excel NETWORKDAY INTERNATIONAL function

**Excel NETWORKDAYS INTERNATIONAL Function – Syntax & Arguments**

=NETWORKDAYS.INTL(start_date, end_date, [weekend], [holidays])

**start_date –**a date value that represents the start date.**end_date**– a date value that represents the end date.**[weekend] –**(Optional) Here, you can specify the weekend, which could be any two days or any single day. If this is omitted, Saturday and Sunday are taken as the weekend.**[holidays]**– (Optional) It is a range of dates that are excluded from the calculations. For example, these could be national/public holidays. This could be entered as a reference to a range of cells that contains the dates, or could be an array of serial numbers that represent the dates.

Now let’s see an example of calculating the number of working days between two dates where the weekend days are Friday and Saturday.

Suppose you have a dataset as shown below:

To calculate the number of working days (Column D) with the weekend as Friday and Saturday, use the following formula:

=NETWORKDAYS.INTL(B2,C2,7,$F$2:$F$6)

The third argument in this formula (the number 7) tells the formula to consider Friday and Saturday as the weekend.

## Calculating the Number of Weekends Between Two Dates in Excel

We can use the NETWORKDAYS function to calculate the number of weekends between two dates.

While the Networkdays function calculates the number of working days, we can also use to get the number of weekend days between two dates.

Suppose we have a dataset as shown below:

Here is the formula that will give you the total number of weekends days between the two dates:

=DAYS(C2,B2)+1-NETWORKDAYS(B2,C2)

## Calculate the Number of Work Days in a Part-time Job

You can use the Excel NETWORKDAYS.INTL function to calculate the number of work days in a part-time job as well.

Let’s take an example where you are involved in a project where you have to work part-time (Tuesday and Thursday only).

Here is the formula that will get this done:

=NETWORKDAYS.INTL($B$3,$C$3,"1010111",$E$3:$E$7)

Note that instead of choosing the weekend from the drop down that’s inbuilt in the function, we have used **“1010111” ***(in double quotes).*

- 0 indicates a working day
- 1 indicates a non-working day

The first number of this series represents Monday and the last number represents Sunday.

So “0000011*“* would mean that Monday to Friday are working days and Saturday and Sunday are non-working (weekend).

With the same logic, **“1010111”** indicates that only Tuesday and Thursday are working, and rest 5 days are non-working.

In case you have holidays (which you don’t want to get counted in the result), you can specify these holidays as the fourth argument.

## Calculate the Number of Mondays Between Two Dates

To find the number of Mondays between two dates (or any other day), we can use the same logic as used above in calculating part-time jobs.

Suppose you have a dataset as shown below:

Here is the formula that will give you the number of Mondays between the two dates:

=NETWORKDAYS.INTL(B2,C2,”0111111″)

In this formula, 0 means a working day and 1 means a non-working day.

This formula gives us the total number of working days considering that Monday is the only working day of the week.

Similarly, you can also calculate the number of any day between two given dates.
