Calc Days from Date


#1

Hello.
I am Ruby Beginner. Now I am trying to write a code, that calcs days
between two dates.

I ask the user for a date. Then the User type a german Date (for
example 12.06.2006). This is working well. Now, what does I have to do
to calc the days between now and the date which has the user give in?

Thanks for your help.

tday = Date.today
bday = Date.new(2009, 4, 30)

days = (bday - tday).to_i => 201

Hi Michael

Thank you for your help. I have now done it with the fallowing code:

datum = Date.Parse(datums)
seconds = Time.Now-datum

This is also working. The variable datums holds a date which is the
user give in over the console. Could there be a problem with my code?

Well, there’s no Now method.

There are so many ways people writes a date so it is to be expected to
have problem if you aloud free form input.
If datums have a time component the things become even more
interesting.
Parsing the user input is always a tricky business.
