Basic Examples of Using NETWORKDAYS.INTL Function:
In the following example, I have explained how to use the NETWORKDAYS.INTL function to calculate working days with three different scenarios: No weekends, Saturday and Sunday as weekends, and only Sunday as a weekend. I have also used both code formats (Binary and Numerical) to identify holidays. Please take a look.
The Example seems to be simple, but it is effective for quick understanding.
Explanation of the above Example:
- In this example, the formula =NETWORKDAYS.INTL(B3, C3, “0000011”, L$3:L$4) calculates the number of working days between January 2, 2024, and January 31, 2024, while excluding weekends and holidays.
- The code “0000011” tells Excel that Saturday and Sunday are considered weekends. The holiday list in cells L3:L4 includes January 1, but since it falls outside the date range, only weekends are excluded.
- Since January 2024 has 8 weekend days, Excel subtracts these from the total 31 days of the month, resulting in 22 working days.
How the NETWORKDAYS.INTL Calculates the Working Days
Is There any Manual Formula Available to Replicate the NETWORKDAYS.INTL Functionality?
