We are using the WORKDAY formula to create a construction schedule returning dates for each task.

Start Date 12/22/05 (Keyed Date) Cell B1
Slab Date =workday(B1,2,Holidays)
Formula Returns 12/27/05 Cell B2
Inspection =workday(B2,1,Holidays)
Formula Returns 12/28/05 Cell B3

This is we want to use a 6 day work week. How can this formula be modified to acknowledge Saturday as a working day?

Appreciate the help!!!

Excel Facts

Enter current date or time
Ctrl+: enters current time. Ctrl+; enters current date. Use Ctrl+: Ctrl+; Enter for current date & time.
6 day Work Week

OK...I have noticed that a number of people have viewed this question but no one has replied.

Have I worded the question properly? Or, is there just not a formula or an easy way to extend the work week to include Saturday and return work day dates accordingly?

If I need to better explain the question....please let me know.

Thanks again.

Schedule Generator using 6 Day Work Week excluding Holidays

Thanks for the replys. I had looked at the TOPIC referenced below, but it did not address holidays.

The second posting dealt with Holidays but it calculated NET DAYS...thus it delivers a count.

BUT, my problem is HOW to convert this into a schedule that returns the Workday function does. Thus you start with a given date, provide a number of days for task completion, which is then added to the prior date excluding ONLY Sundays and Holidays as work days.

I can't seem to figure out how to make a SCHEDULE work.

I believe the following will work for you, although I have no experience with the Workday function so some adjustment may be needed. I'm assuming you want to skip all Sundays and all holidays as possible End dates, but allow Saturdays. The example below shows the behavior of the formula on intervals containing holidays.

6 Day Work Week

The array formula (entered with CTRL-SHIFT-ENTER) in C2, and copied down, is:


Some notes and caveats:

In order for the MATCH usage to work correctly, the Holidays list (E2:E12 in the example) must be sorted in ascending order and a dummy date for the first holiday (smaller than any start date you'll be using) is needed, as I've shown.

The 1000 number is an arbitrary choice -- it must be large enough to cover the number of total days needed in any of your task periods. If you wish to adjust this, do so in all instances of ROW($1:$1000).

If you must allow for possible deletions or insertions of rows above any cell containing the formula, then all instances of ROW($1:$1000) (or whatever you choose) should be replaced by


The formula isn't efficient, but making it so would make it longer, and besides, I've struggled long enough with this as it is.
