Entering a date in the form dd/mm/yyyy

Send("{UP}{UP}{UP}{UP}{CTRLDOWN}b{CTRLUP}{TAB}{TAB}{PGUP}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{DOWN}{TAB}??????????{TAB}{TAB}{CTRLDOWN}b{CTRLUP}{ENTER}")

I am trying to do 2 things, but getting nowhere, firstly can autoit replace the ????? in the above script to the current day in the form dd/mm/yyyy

And then when I tab to another entry box not defined in the above script, do a calculation current date - 365 days?

Thanks
