Date matching formulas

Three formulas make date-based comparisons easier and more intuitive. Use MATCHWEEK, MATCHMONTH, and MATCHYEAR to convert any date value into it’s respective week, month, or year.

Previously, you'd need to:

• Extract the week number and year from your date field in order to reference it in your formula.
• Now, write your formula to match on both week number and year: =countifs(D:D,weeknum(H2),E:E,year(H2)).

Now, you can:

• Skip the calculated column and enclose the date value in a MATCHWEEK / MATCHYEAR formula: =countifs(A:A,matchweek(F2),A:A,matchyear(F2)).
