no, it`s for my web page

i tryed to do that in php in this way:

i keept in mind that all months have 31 days and after adding 2 moths ( in my example 2.54 ) ( never mind to wich date ) i calculated how much days i should take of ( for example if month 2 have 28 days and i keept in mind that all month have 31 days so for that month i must take - 3 days ) and after that i added thous 0.54 of that month days.

but its dificult to test all posibilities of errors and in some ways i get few days in answer bad.

i got errors when i was calculated end of months wich ones have 30;29;28 days

so in php my experianse is to week, but i practise bash sh languages, so i`m asking meaby there is any simple way to calculate it ( meaby use unix time ( meaby it have some extensions for it ) ) in bash sh ( if yes then ill simple from my web page will shell_exec to bash and ill take the values from it )
