NETWORKDAYS (start_date,end_date,holidays)

where,

• start_date represents the starting date,
• end_date represents the end date, and
• holidays is an optional range of one or more dates to exclude from the working days.
• NETWORKDAYS() returns the number of whole workdays between two dates.

## Description

NETWORKDAYS(start_date, end_date, holidays)

• start_date, end_date and holidays should be entered either in 'date format' or 'dates returned using formulas'.
• If date values are invalid, Calci displays #NULL error message.
• We can use the DD/MM/YYYY format also. For Example:"14/5/2005[DD/MM/YYYY]".
• We can use Range values also. For Example: NETWORKDAYS(DATE(2012,6,1),#12/31/2012-12/31/2013)
• #date notation needs mm/dd/yy format .
