I have been trying to figure out a formula to show how many days a project would take if a start date was given and hours of project assuming a person worked 8 hrs per day. See example below. I used the formula
MIN(D$3-SUM($F$3:G3),8), which will "spread" the "8" until it reaches "0", but when i tried to trigger when a date is reached, =IF(C$3>=J$1,MIN(D$3-SUM($F$3:G3),8),0), it only shows 1 date with an "8" in it. I tried calculating end date using WORKDAYS(C$3,D$3/8) which is 1/15/2020, but couldn't figure out how to stop at end date. Is this possible? Examples of how data should look below.

Copy formula down without changing references
If you have =SUM(F2:F49) in F50; type Alt+' in F51 to copy =SUM(F2:F49) to F51, leaving the formula in edit mode. Change SUM to COUNT.
Starting in F1 try :=IF($C3>=F$1,MIN($D3-SUM($E3:E3),8),0)
pull right and down

Try this
Rich (BB code):
=IFERROR(IF(AND(F$1>=$C3,DATEDIF($C3,F$1,"D")<$D3/8), 8, ""),"")

Just noticed you skip weekends in your dates. Try this instead
Rich (BB code):
=IFERROR(IF(AND(F$1>=$C3,NETWORKDAYS($C3,F$1)<=$D3/8), 8, ""),"")
