Hello,

Hello, I'm trying to write a formula that will recalculate a date based on a fixed number of days.

For example I have 2/1/19 in cell A42. In cell A41 I would like to show what that date would be if I subtracted 1 day, the result being 1/31/19.

But what, there's more. If. using the example above, the result for A41 was a weekend or holiday, I would like the formula to calculate that and back that date up to the next weekday/non holiday.

I have a spreadsheet I can provide if anyone would like to see it.

Is this possible? Thanks in advance everyone.

Hi Blair,

You are looking for the WORKDAY.INTL function.

WORKDAY.INTL(start_date, days, [weekend], [holidays])

Formula for A41:
=WORKDAY.INTL(A42,-1,1,\$B\$1:\$B\$20)
start_date: take the date from A42.
days: subtract 1 day
[weekend]: the 1 here means weekend is Saturday and Sunday.
[holidays]: This is the range where you have listed the holidays. Adjust the range to match yours.

Drag formula up.

Best regards,
Trowa

Perfect thanks Trowa. The only thing I'm not clear on is "[holidays]: This is the range where you have listed the holidays. Adjust the range to match yours." Can you help me understand?

Sure, lets say 1/28/2019 till 2/1/2019 is holiday. Then put 1/28/2019, 1/29/2019, 1/30/2019, 1/31/2019, 2/1/2019 in range B1:B5 and use that range as your holiday range. Use \$ symbols to make the range fixed, so it stays the same when you drag the formula.
