Number counts within Date Range

[SteveStats]

I have about 45 different dates ranging from March through October (this
year) in one column. I want to bounce off today's date (NOW()) to count how
many of these items are <30 days old, 31-60 days old, 61-90 days old and
91+days old.

You have a few options...
Explore these:

30 or less:
=COUNTIF(A1:A300,">="&TODAY()-30)


31 thru 60:
=INDEX(FREQUENCY(A1:A300,TODAY()-{61,31}),2)
or
=COUNTIF(A1:A300,">="&TODAY()-60)-COUNTIF(A1:A300,">="&TODAY()-30)
or
=SUM(COUNTIF(A1:A300,">="&TODAY()-{60,30})*{1,-1})


61 thru 90:
=INDEX(FREQUENCY(A1:A300,TODAY()-{91,61}),2)
or
=COUNTIF(A1:A300,">="&TODAY()-90)-COUNTIF(A1:A300,">="&TODAY()-60)
or
=SUM(COUNTIF(A1:A300,">="&TODAY()-{90,60})*{1,-1})


Over 90:
=COUNTIF(A1:A300,"<"&TODAY()-90)

Adjust range references to suit your situation.

Does that help?

Assuming source dates (real dates) are within A2:A10 with no blank cells,
and tightened limits with no gaps

<=30 days
=SUMPRODUCT(--(TODAY()-A2:A10<=30))

31-60 days
=SUMPRODUCT((TODAY()-A2:A10>30)*(TODAY()-A2:A10<=60))

61-90 days
=SUMPRODUCT((TODAY()-A2:A10>60)*(TODAY()-A2:A10<=90))

90 days

=SUMPRODUCT(--(TODAY()-A2:A10>90))

Adapt the dates range A2:A10 to suit your actual range
