The easiest way is to select your data, insert pivot table, put the day as a row field, and as a data fields, then right click the row field and Group by day. This will give you a table with a count of occurrences by day.

If you don't have different times and only days, you can skip the grouping part.

this formula will count only the day elements
=COUNTIFS($A$1:$A$36,">="&INT(A1),$A$1:$A$36,"<"&INT(A1+1))

but it will repeat the count for each date entry

Assuming list of dates and times in column A andseparate list of individual dates in column D:

=COUNTIFS($A$3:$A$37,"<"&$D3+1,$A$3:$A$37,">="&$D3)

D3 being day to be counted.

Counts entries where value is less than next day and greater than or equal to current day. Time in excel is recognised as a decimal part of a day so does same as INT part of regmigrant's suggestion but puts date in separate column so no repeats.

Alternative, get round repeats using an IF statement comparing the date parts for movement to next day:

=IF(INT($A4)=INT($A3),"",COUNTIFS($A$1:$A$38,">="&INT(A3),$A$1:$A$38,"<"&INT(A3+1)))

Puts count against last entry of each day.

Thanks
