Find beginning/start of week by a given date with formulas

This method will introduce some formulas to find the beginning/start of week by any given date in Excel easily.

Formula: =A2-WEEKDAY(A2,2)+1

Select a blank cell where you will return the beginning of week, and enter the formula =A2-WEEKDAY(A2,2)+1 (A2 is the cell with given date) into it, and drag the Fill Handle to the range as you need. See screenshots:

Note: This formula =A2-WEEKDAY(A2,2)+1 will return Monday as the beginning of week based on the given date.

Formulas: =A2-MOD(A2-2,7) or =A2-MOD(A2-1,7)

Select a blank cell you will return the beginning of week, and enter the formula =A2-MOD(A2-2,7) (A2 is the cell with given date) into it, and then drag the Fill Handle to the range as you need. See screenshots:

Notes:

(1) This formula =A2-MOD(A2-2,7) will return Monday as the beginning of week based on the given date. For returning Sunday as the start of a week, please apply this formula =A2-MOD(A2-1,7).

(2) If returned Monday or Sunday doesn’t show as date, please keep selecting the dates and click the Home > Number Format drop down list > Short Date. See screenshot:

Hi there,

I guess the date of the "TODAY()" when you leave this comment is 5/1/2022, right?

Since Excel uses the international standard ISO 8601, which means Monday is the first day of the week. So, if today is 5/1/2022, that means "this week" is from 4/25/2022 to 5/1/2022.

This works....

=TEXT((TODAY()+2)-WEEKDAY(TODAY(),1),"mm.dd.yyyy") & " - " & TEXT((TODAY()+6)-WEEKDAY(TODAY(),1),"mm.dd.yyyy")

Thanks for the Formulas: =A2-MOD(A2-2,7) or =A2-MOD(A2-1,7).
