We have taken 1st January 2019 as Start date and 31st December 2019 as End date and will be calculating net working days during a period of one year. Following the syntax, we have 261 net working days during that period
Example 2: Networkdays Function with(Holidays) option
We have taken 1st January 2019 as Start date and 31st December 2019 as End date and have a list of holidays.
Net working days will be calculating considering 1st Jan 2019 as Holiday and total net working days for a year will be 260.
Example 3: Networkdays function with Date prior to 1st january 1900
We mentioned that Microsoft Excel will calculate the date functions starting from 1st January 1900 and if we use any date prior 1st January 1900 this will show as #VALUE! (Error)
We have taken 1st January 1889 as Start date and 31st December 1889 and since it is prior to 1st January 1900 output is shown as #VALUE! (Error)
