Getting number of days in a month

Rails
1

In PHP, there was an argument you could pass to the Date function to
get the number of days in the current month:

echo date(“t”); // Outputs “28” for February

I don’t see anything like this in Ruby/Rails. Right now, I’m using a
very ugly line to pull the last day of the month:

@number_of_days = (Date.strptime(Date.today.strftime("%Y-%m-01")) >>

    • 1

Basically, it takes the first day of the current month, adds one
month, and then subtracts one day. Am I completely overlooking some
obvious and easy way to do this? (I’m assuming so).

Hey,
This should work.

@number_of_days = Date.civil(year, month, -1).day

Cheers,

oops …

today = Date.today
@number_of_days = Date.civil(today.year, today.month, -1).day

How about using:

Time.days_in_month(month, year=nil)
