Count number of days between two dates

Question

How do I count the number of days between these two dates?

start_date = Date.parse \"2012-03-02 14:46:21 +0100\"
end_date =  Date.parse \"2012-04-02 14:46:21         


        

Answer 1

to get the number of days in a time range (just a count of all days)

(start_date..end_date).count
(start_date..end_date).to_a.size
#=> 32

to get the number of days between 2 dates

(start_date...end_date).count
(start_date...end_date).to_a.size
#=> 31
