Start Date and End Date

[Edward VN]

I have a field with a date picker, how can i add 4 years to this date and
make it return the future date (taking into account leap years etc)

I've only figured how much time has elapsed between two dates but you might
find some info here http://enterprise-solutions.swits.net/ then select
the infopath version to the right.

Hope this helps.
