    I'm sorry to say that only 2 (out of 5) formulas are capable to handle a 24 hours shift (Col. G & I)
    As for the formula in Col. J - try:
    START: 06:00 AM
    END: 11:30 PM
    and you'll get a round(!) figure of 17.00 instead of 17.30 hours and so poor Billy lost half an hour...
    Multiply that lost 25
    I rest my case.

    @achuyth,
    You may try via Mail: micky-atapuz.co.il
    Please try to avoid as much as possible because my spare time is very short.
    Please remember that my mother's tongue was not English - so, please, write in details & attach a sample workbook.
