Count the number of hours within a certain range on excel -



Count the number of hours within a certain range on excel -

i wanting enhance functionality of time sheet. want calculate if person's hours falls range, , if so, count how many hours. example:

a user clocks in on time sheet: tuesday: 05:00 - 04:00 i.e. - worked 23 hours.

from above time, want count how many hours have worked between time range 19:30 - 07:30.

manually calculating works out @ 9.5 hours - or 09:30.

many thanks.

this working me in cases i've tested:

data cells:

a1: range start | b1: range end

a2: clock in       | b2: clock out

formula:

=if(b2<a1,0,if(a2>b1,0,if(a2<a1,if(b2>b1,b1-a1,b2-a1),if(b2>b1,b1-a2,b2-a2))))

the result in days, if want in hours, multiply 24.

=if(b2<a1,0,if(a2>b1,0,if(a2<a1,if(b2>b1,b1-a1,b2-a1),if(b2>b1,b1-a2,b2-a2))))*24

if times span more 1 day, it's crucial work cells include date. in excel, if come in time, (fake) date 00/01/1900, ending times have appropriate date, specified next day: 01/01/1900. therefore, if have time, have well.

but if total datetime from, example, database, won't have issue, have modify range cells have corresponding dates, or modify clock cells convert date 00/01/1900, depending on scenario. please give more details if need help this.
