Also, Microsoft Excel calculate dates from 1st January 1900, if you use any date before than 1st January 1900 it will be shown as #VALUE! (Error)

Below is the NETWORKDAYS Formula syntax used in Excel:

`Syntax: =NETWORKDAYS(start_date, end_date, [holidays])`

Start_date argument is the date from which workday will be calculated. This date can be a working day or weekend, past day or future day.

End_date argument is the date to which workday will be calculated.

[holidays] Argument (Optional), Holidays argument is optional argument and used to excludes the holidays from NETWORKDAYS function output. We can give the complete range to exclude such days. Holidays are exception dates and such dates will not be counted as workdays (even those are falling on Monday to Friday)

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

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.

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)
