5 Excel Workday Formulas

Introduction to Excel Workday Formulas

Excel workday formulas are used to calculate dates and times in a way that excludes weekends and holidays, which is essential for business and project management. These formulas help you determine the number of workdays between two dates, add or subtract workdays from a date, and more. In this article, we will explore five essential Excel workday formulas that you can use to streamline your workflow and improve productivity.

1. NETWORKDAYS Function

The NETWORKDAYS function is one of the most commonly used workday formulas in Excel. It calculates the number of workdays between two dates, excluding weekends and holidays. The syntax for this function is: NETWORKDAYS(start_date, end_date, [holidays]) Where: - start_date is the starting date of the period. - end_date is the ending date of the period. - [holidays] is an optional range of dates that are considered holidays.

For example, if you want to calculate the number of workdays between January 1, 2022, and January 31, 2022, and you have a list of holidays in the range A2:A10, you can use the following formula: =NETWORKDAYS(A1, B1, A2:A10)

2. WORKDAY Function

The WORKDAY function is used to add or subtract a specified number of workdays from a date. The syntax for this function is: WORKDAY(start_date, days, [holidays]) Where: - start_date is the starting date. - days is the number of workdays to add or subtract. - [holidays] is an optional range of dates that are considered holidays.

For example, if you want to add 10 workdays to January 1, 2022, and you have a list of holidays in the range A2:A10, you can use the following formula: =WORKDAY(A1, 10, A2:A10)

3. NETWORKDAYS.INTL Function

The NETWORKDAYS.INTL function is similar to the NETWORKDAYS function, but it allows you to specify the weekend days. The syntax for this function is: NETWORKDAYS.INTL(start_date, end_date, [weekend], [holidays]) Where: - start_date is the starting date of the period. - end_date is the ending date of the period. - [weekend] is a number that specifies the weekend days (1 = Saturday and Sunday, 2 = Sunday and Monday, etc.). - [holidays] is an optional range of dates that are considered holidays.

For example, if you want to calculate the number of workdays between January 1, 2022, and January 31, 2022, and you have a list of holidays in the range A2:A10, and you want to consider Monday and Tuesday as weekend days, you can use the following formula: =NETWORKDAYS.INTL(A1, B1, 3, A2:A10)

4. WORKDAY.INTL Function

The WORKDAY.INTL function is similar to the WORKDAY function, but it allows you to specify the weekend days. The syntax for this function is: WORKDAY.INTL(start_date, days, [weekend], [holidays]) Where: - start_date is the starting date. - days is the number of workdays to add or subtract. - [weekend] is a number that specifies the weekend days (1 = Saturday and Sunday, 2 = Sunday and Monday, etc.). - [holidays] is an optional range of dates that are considered holidays.

For example, if you want to add 10 workdays to January 1, 2022, and you have a list of holidays in the range A2:A10, and you want to consider Monday and Tuesday as weekend days, you can use the following formula: =WORKDAY.INTL(A1, 10, 3, A2:A10)

5. Calculating Workdays between Two Dates with Holidays

To calculate the number of workdays between two dates with holidays, you can use the following formula: =NETWORKDAYS(start_date, end_date, holidays) Where: - start_date is the starting date of the period. - end_date is the ending date of the period. - holidays is a range of dates that are considered holidays.

For example, if you want to calculate the number of workdays between January 1, 2022, and January 31, 2022, and you have a list of holidays in the range A2:A10, you can use the following formula: =NETWORKDAYS(A1, B1, A2:A10)
