Not if you can't ask something that's understandable.
I can't cook, so I send you this problem:
apples cost $3.25 for a dozen;
how long must I cook 3 of them, to make an apple pie?
What would you answer if you're a good cook?
Your problem statement(s) is a bit similar!
From what I remember of the boring accounting course I once took,
it seems you're trying to figure out a "month-end adjusting entry"
in order to more accurately reflect the month's payroll expenses.
There is no "formula" as such for this: the payroll expense G.L.account
has been either understated (like, up to 28th in a 30 day month) or
overstated (like, up to 2nd of following month).
So a "2day adjustment" has to be made, up or down depending on above.
Such a calculation is usually an in-house "guess", like averaging the last
complete pay-period; the "head accountant" usually steps in and does
some calculation intended to impress the junior accountants :wink:
