Date from GNU to BSD

Dear all,

This should be simple but I cannot figure it out despite reading all the man pages. Could someone please help me translate this code (GNU date) to one that can be read by BSD date?:

myDate=$(date -d "$h -$l days" +%Y/%m/%d),

where h is a variable of the form DD/MM/YYYY, and l is a simple integer.

So basically, I want to take the date that is stored in h, add l days to it, and format it as YYYY/MM/DD.

Alternatively, is there a way to force my mac to use GNU date instead of BSD date?

Thank you!
Tom

Should work in any shell, but requires GNU date, although GNU date seems only to be happy for input dates between 1902 and 2037, inclusive (49673 days).
