星期四 =IF(MOD(A2-1,7)>4,A2+4-MOD(A2-1,7)+7,A2+4-MOD(A2-1,7))
星期三 =IF(MOD(A1-1,7)>3,A1+3-MOD(A1-1,7)+7,A1+3-MOD(A1-1,7))
;週二 =IF(MOD(A1-1,7)>2,A1+2-MOD(A1-1,7)+7,A1+2-MOD(A1-1,7))

Thanks for your reminder, the original formula is not enough rigorous indeed. I have updated the formulas and rewrited the tutorial, hope the new formulas can help you.

Im trying to work out how to use a date, less an amount of days but ensure when subtracting the days it lands on a weekday not a weekend.
Any formulas??

Hi Everyone,
I use the formula below to round to the next Thursday where A1 is the cell with your original date and 14 is for Thursday. You can use other numbers for other days if required. 11=Monday, 12=Tuesday, 13=Wednesday, etc...

Also, you can use a 1 instead of an 8 to get the Thursday before your original date in A1. If your original date is already a Thursday the formula will produce the same date as in A1.

I hope this helps!

=A1+(0-WEEKDAY(A1,14)+8)

hi guys,

I used the formula below, I hope it works for you.
IF(WEEKDAY(H2,16)<>7,(7-WEEKDAY(H2,16))+H2,H2) where H2 is the date that you want to round up to the next day of the week (in my case for Friday) and the 16 is the format to start the date with Saturday as #1 and Friday as #7.

Your round to previous Sunday is flawed. Even shows as much on your sheet.

So, what would be the correct formula to first check to see if a cell has a date, else leave it blank and make the date the fall on a Friday before if the date falls on a Saturday or Sunday?

I found a workaround for to the previous Friday. You can change the switch "results" as needed to round to different days.=H3-SWITCH(TEXT(H3, "DDD"), "Mon", 3, "Tue", 4, "Wed", 5, "Thu", 6, "Fri", 0, "Sat", 1, "Sun", 2)
=[date]-SWITCH(TEXT([date], "DDD"), "Mon", 3, "Tue", 4, "Wed", 5, "Thu", 6, "Fri", 0, "Sat", 1, "Sun", 2)
