Calculate number of 8 hour days a date range
With the start date/time in A1 and the end date/time in B1:
=LET(startdate, A1, enddate, B1, wholedays, INT(enddate-startdate), newstart, startdate+wholedays, starttime, MIN(MAX(MOD(newstart, 1), TIME(8, 0, 0)), TIME(16, 0, 0)), endtime, MAX(MIN(MOD(enddate, 1), TIME(16, 0, 0)), TIME(8, 0, 0)), partday, MOD(endtime-starttime, TIME(8, 0, 0))/TIME(8,0,0), wholedays+partday)
Do you want to include or exclude weekend days?
And how do you want to count partial days, such as 29.01.2023 in your example (up to 13:30 instead of 16:00)?
Thank you for your reply.
R.e. weekends I want to include these.
R.e. partial days I'd like to count these as a part of a day e.g. 08:00 to 13:30 would be 0.6875 days.

HansVogelaar I've had to move some cells and the start date is now in cell X1 and the end date in cell Y1. I've tried changing A1 for X1, and B1 for Y1 in the formula but the error "#NAME?" comes up. Do you know why this may be?
This doesn't work?
=LET(startdate, X1, enddate, Y1, wholedays, INT(enddate-startdate), newstart, startdate+wholedays, starttime, MIN(MAX(MOD(newstart, 1), TIME(8, 0, 0)), TIME(16, 0, 0)), endtime, MAX(MIN(MOD(enddate, 1), TIME(16, 0, 0)), TIME(8, 0, 0)), partday, MOD(endtime-starttime, TIME(8, 0, 0))/TIME(8,0,0), wholedays+partday)
Are you using a different version of Excel than before?
