Days Until Next Event
Scenario: A list contains items which have a recurring date. Anniversary, birthday, things like that. We want to calculate how many days remain until the next occurrence of that event.
Solution: Create a calculated column to calculate the number of days from today until the next occurrence. But today isn't available in a calculated column, you say? Bah...Head on over to Mark Kruger's blog for a quick work around to be able to use Today in a calculation. Cool.
Anyway, once you do that, all you need is the calculation (DOB is my column for, well, date of birth):
=DATE(IF(OR(MONTH(DOB)<MONTH(Today), AND(MONTH(DOB)=MONTH(Today), DAY(DOB)<DAY(Today))),YEAR(Today)+1,YEAR(Today)), MONTH(DOB), DAY(DOB))-Today
This Today workaround really opens some doors that were previously closed. Thanks Mark!
