How to use NETWORKDAYS.INTL function in Google Sheets
- Type “=NETWORKDAYS.INTL” or go to the “Insert” tab ➝ “Function” ➝ “Date” ➝ “NETWORKDAYS.INTL”.

Syntax
NETWORKDAYS.INTL(start_date, end_date, [weekend], [holidays])
- start_date – The start date of the period from which to calculate the number of net working days.
- end_date – The end date of the period from which to calculate the number of net working days.
- weekend – [ OPTIONAL – 1 by default ] – A number or string representing which days of the week are considered weekends.
- String method: weekends can be specified using seven 0’s and 1’s, where the first number in the set represents Monday and the last number is for Sunday. A zero means that the day is a work day, a 1 means that the day is a weekend. For example, “0000011” would mean Saturday and Sunday are weekends.
- Number method: instead of using the string method above, a single number can be used. 1 = Saturday/Sunday are weekends, 2 = Sunday/Monday, and this pattern repeats until 7 = Friday/Saturday. 11 = Sunday is the only weekend, 12 = Monday is the only weekend, and this pattern repeats until 17 = Saturday is the only weekend.
- holidays – [ OPTIONAL ] – A range or array constant containing the dates to consider as holidays.
- The values provided within an array for holidays must be date serial number values, as returned by N or date values, as returned by DATE, DATEVALUE or TO_DATE. Values specified by a range should be standard date values or date serial numbers.
