Calculate # of days from start & finish dates etc.

[KJG03]

Hi all. I'm needing to calculate the number of days employed for the financial year if there is either a start and/or a finish date. But if both are blank, as it is for the employee in Row 7, then I need it to return the value of 365.
Hoping you can help. See below screenshot. Thanks in advance.

=IF(AND(J7="",K7=""),365, "your formulas for working out dates when there is an entry")

Thanks Wayne. The first part is a great help. I'm also getting stuck on what the rest would be as I need it to calculate days worked in the year if either start or finish dates are entered or both have an entry. That's why I have the start of Financial Year and End of Financial Year dates in cells L3 & L4 to use as a calculation base. But just not sure how to include all those variables in the formula.

just checking the rules
if the startdate is blank, but the end date is not
then you want to use L3 at the start date (in your example) and K8 as your end date - However, K8 is greater than the end of the fiscal - so would that be 365 as well.

If the start date (J8) is before the fiscal start and the enddate (K8) is after the fiscal end , then is that also 365

so above we now have 3 rules for putting in 365

after those tests , then the start date (J6) and end date (K6) will have dates in that are within the fiscal or one of the cells is blank

then we have 3 calculations to make
J6 and K6 have dates in
so its just K6-J6
J6 is blank but K6 is not - and we know it must have a date that is not greater than the fiscal end
K6 - $L$3

K6 is blank but J6 is not - and we know it must have a date that is not greater than the fiscal end
$L$4 - J6

is that all the logic to test
if so we can use a combination of Nested ifs and ANDs
But first can we just check that all the possible entries and scenarios and the results needed

Welcome to the MrExcel board!

Try this, copied down.
Note that this will return 366 for a full year if the year includes a leap-year February. Is that what you want?

Perfect! Thanks so much Peter.

Thanks Wayne. Yes I should have had 30/6/19 as the end date. Peter's solution worked.
