Specifying Different Weekends with NETWORKDAYS

Sunil can use the NETWORKDAYS function to return the number of regular business days between two dates. The function assumes that Saturday and Sunday are not work days, but in Sunil's organization only Sunday counts as a non-work day. He wonders if there is a way to use NETWORKDAYS and specify that only Sunday should be excluded from the count returned.

You can determine this by using a formula based on the NETWORKDAYS function. Assuming that the starting date is in A1 and the ending date is in B1, the following formula examines the days between the two dates and essentially return a count of non-Sunday days in that range:

=NETWORKDAYS(A1,B1)+SUMPRODUCT(--(WEEKDAY
(ROW(INDIRECT(A1&":"&B1)))=7))

Of course, since Sundays are the only day of the week being excluded, you could simply skip the use of NETWORKDAYS and use SUMPRODUCT to figure out if the day should be counted or not:

=SUMPRODUCT(--(WEEKDAY(ROW(INDIRECT(A1&":"&B1)))>1))

If you expect that there may be holidays in the range, and that those holidays are in the named range “holidays,” then you'll need to go back to using NETWORKDAYS in the formula:

=NETWORKDAYS(A1,B1,holidays)+SUMPRODUCT(--
(WEEKDAY(ROW(INDIRECT(A1&":"&B1)))=7),--
(NOT(ISNUMBER(MATCH(ROW(INDIRECT(A1&":"&B1))
,holidays,0)))))

Of course, if you are using the latest versions of Excel (beginning with Excel 2010), you can use the NETWORKDAYS.INTL function, which does more than the older NETWORKDAYS function. The biggest difference between the two is that NETWORKDAYS.INTL allows you to specify how the function should handle weekends. So, for instance, in Sunil's case where only Sundays should be considered "the weekend," you could use the following formula:

=NETWORKDAYS(A1,B1,11,Holidays)

Note that the only difference between this and full version of the NETWORKDAYS function is the inclusion of a new third parameter. In this case, the value 11 indciates that only Sundays should be considered weekends, but you could use any other the other parameter values, depending on your needs.

Number Weekend Days
1 Saturday, Sunday
2 Sunday, Monday
3 Monday, Tuesday
4 Tuesday, Wednesday
5 Wednesday, Thursday
6 Thursday, Friday
7 Friday, Saturday
11 Sunday
12 Monday
13 Tuesday
14 Wednesday
15 Thursday
16 Friday
17 Saturday

You can perform other magic with NETWORKDAYS.INTL, as well, but that is best left to different ExcelTips.

Having introduced the NETWORK.INTL function, the last formula should be:
=NETWORKDAYS.INTL(A1,B1,11,Holidays)
