To generate a dynamic series of dates that include only certain days of the week (i.e. only Tuesdays and Thursdays) you can use the WORKDAY.INTL function. In the example shown, the date in B5 is a hardcoded start date. The formula in B6 is:
The formula returns only Tuesdays and Thursdays as the formula is copied down. If the start date in B5 is changed, new dates are dynamically generated.
The WORKDAY.INTL function is normally used to find dates that are workdays. For example, you can use WORKDAY.INTL to find the next workday that is not a weekend or holiday, or the first workday 5 days from now.
One of the the arguments provided to WORKDAY.INTL is called "weekend", and controls which days are considered non-working days. The weekend argument can be provided as a number linked to a preconfigured list, or as a 7-character code that covers all seven days of the week, Monday through Saturday. This example uses the code option to "filter out" days that are not Tuesdays or Thursdays.
In the code, 1's represent weekend days (non-working days) and zeros represent work days, as illustrated with the table in D4:K9. We only want to to see Tuesdays or Thursdays, so we use zeros for these days, and 1's for every other day:
With a given start date, the WORKDAY function will return a date that is not a weekend or holiday, n days in the future or past. The holidays argument is optional and can be omitted. In the example, B5 a the hard-coded start date. The formula below...
The WORKDAY.INTL function is normally used to generate dates that are workdays. For example, you can use WORKDAY.INTL to find the next workday that is not a weekend or holiday, or the first workday 10 days from now. One of the the arguments provided...
The Excel WORKDAY.INTL function takes a date and returns the nearest working in the future or past, based on an offset value you provide. Unlike the WORKDAY function, WORKDAY.INTL allows...
