Days since string

hey is it possible to do a “days since string”

exsample: if i want to know how many days past since 24/12/2001 = 5617 (including the first day and current day)

how this is possible and someone wants to help.

thx

Hey Infected,
Maybe this countdown post might help

hey i took a look and can’t seem to get my head arround it.

only think it can be used if you want a date within a year.

so don’t think it will work
