I am trying to subtract on date from the other to find how many days
have passed.

I want to know what I need to do to determine

date_sent = 2007-01-01
date_now = Date.today

I want to be able to subtract the date_sent from date_now and return the
accurate number of days that have passed.  Does anyone know how to do
this?  I also what to make sure it actually accounts for months being an
uneven number of days.

Thanks
JP

Hi

number_of_days = (date_now - date_sent).to_i

btw, didn't know this but, Data.parse("2007-01-01") returns the date

works great in the console.

regards
Ivor

date_sent = Date.parse("2007-01-01")
date_now = Date.today

days_passed = (date_now - date_sent).to_i

Subtracting two dates gives a Rational which is the reason for the
integer conversion.

I have done something similar::

date_sent = Date.parse('2007-01-01')
date_now = Date.today

how_many_days_have_passed = (date_now - date_sent).to_i

Hope this helps!

why does it return a Rational type?
