    Need help determining prorated days off based on 90 days after hire date

    I have a feeling this is an easy one, I just can't figure it out despite some googling. I have a spreadsheet that includes hire dates and 90 day marks. If someone is not a new hire and is employed on 1/1 of the year they would be entitled to 9 days off. For new hires, that number is prorated based on the 90 day mark. So if someone's 90 day mark fell on 7/1, they would be entitled to half of 9 days, equaling 4.5 days. Can someone please fill in the blanks for me so that I can prorate the time off based on the 90 day marks listed? Thank you!

    My solution would be..

    but that will give "strange" fractions of days so you might want to round it to half days or full days. Just not sure what you would want.

    Annually 9 days equals 0,75 per full calander month.

    so using datediff would work too

    but that might be a bit strong rounding as difference for apr 1 as 90 day mark = 6 days rather then 6,76 on day based calculation.

    this formula will round to the nearest full hour (based on 8 hour workday)

    last one is most flexible for rounding, replace 1/8 by 1 for full days, or 0,5 for halfdays

    Very helpful! Thank you. I like column B, =DATEDIF(B2,DATE(YEAR(B2),12,31),"M")*9/12. I appreciate your assistance.
