Posted by Jamal Nasir on February 7, 2012 at 3:45 AM Comments comments (1)

Date.new(Time.now.year, 12, 31)

The above line will create a date with the current year, 12 months and 31 days.

(12-Time.now.month)

This will subtract the current month number of month from 12. For example;

If it is Febuary (2), the above line of code will give you 10.

12-2=10

So, the above line will give you the last day of month.
