Excel question - help calculating dates

[icejunkie]

Hi all,
I need to do 2 things:
1) Type in a date in one cell and in another cell have it output that date adding 18 months forward.
2) take the date after 18months were added and add any number of days I want(ie. 13, 165, 219, 54,etc..)and have it output the date with those number of days added.

please help!

thanks in advance

If you've installed the Analysis Toolpack, then you can use the function EDATE

EDATA Function Help

Once you've generated the +18 months date, then just add the number of days you want to generate the correct date.

Assume the original date is in A1.
A2: EDATE(A1,18) would add 18 months to it and fix the date correctly (based on the month).
A3: =A2+41 would add 41 days to the date in A2.
