doc-rabh-go-roimhe-dé Domhnaigh-1
Uaireanta, b’fhéidir go mbeidh ort an lá seachtaine sonrach roimhe sin nó an chéad lá eile ar nós an Domhnaigh a fháil bunaithe ar dháta mar a léirítear an seat scáileáin ar chlé. Anseo soláthraíonn an teagasc seo dhá fhoirmle chun an post seo a láimhseáil go héasca in Excel.

Dáta slánaithe go dtí an lá sonrach seachtaine roimhe sin

mboilgeog cheart gorm saighead Dáta slánaithe go dtí an chéad Lá seachtaine sonrach eile

Mar shampla, anseo chun an chéad Domhnach eile a fháil de na dátaí i gcolún A

1. Roghnaigh cill ar mhaith leat a chur ar an gcéad dáta Dé Domhnaigh seo chugainn, ansin greamaigh nó cuir isteach thíos an fhoirmle:

=IF(MOD(A2-1,7)>7,A2+7-MOD(A2-1,7)+7,A2+7-MOD(A2-1,7))

2. Ansin brúigh Iontráil eochair chun an chéad Domhnach seo chugainn a fháil, a thaispeánfar mar uimhir 5 dhigit, ansin tarraing líonadh uathoibríoch síos chun na torthaí go léir a fháil.

I have entered 11/19/2022
The result was past day 11/18/2022

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)

to clarify, all dates become thursday, but friday and saturday will not convert to the next weeks thursday instead they will go back a day or two to the previous thursday instead going to next weeks thursday, is there any way to fix this in the function =IF(L4="","",L4+4-MOD(L4-1,7))

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)
