Good Afternoon All!

Basic problem, but for some reason none of the things I have tried have
worked. I have created a logbook in excel for myself as a back up to my
pilots logbook. I have it seperating all the data in terms of aircraft type,
aircraft ID, type of flying etc., but what I need is for excel to filter the
past 30 days and 90 days worth of flying, which must be on a rotating basis
(so as we go forward one day, the formula will automatically).

The columns that I have are the Date, Aircraft Type and Rego, Pilot and Co
pilot, and then 16 columns displaying different types of flying (day, night,
single engine, multi engine), and I have 3 sheets to seperate and display the
data.

Please Help!

for 30 days:

your_date =TODAY()-30

90 days:

Your_date =TODAY()-90

So knowing that this is how you get it to display the previous date 30 days
ago, how then do I add the data in the adjoining cells?

Perhaps I need to reword what I want done. :(

What I need is for it to say "OK, this is the date 30/90 days ago, now based
on that how many hours have been flown between this date and todays date"?

I was thinking of some sort of formula like a sumif("x:x", today()-30,
"x:x)) or something like that, but this does not work.
