Rails 3 Finding day of week

I'm trying to make my own calendar because i cant seem to get any help with event calendar so what im trying to do is Display the day of the week ie.. January 1 2011 is a Saturday is there an e开发者_运维知识库asy command to get that day or do i need something else

You can also get the string, like "Wednesday", using time.strftime("%A")

Can't you use time.wday, 0 = sunday and so on

Actively using in Rails 4 - should in most other versions as well...

Both of these options will give you the day string (eg. "Saturday") for the date specified:

Specific date:

Date.new(2011, 1, 1).strftime('%A') # returns "Saturday"

Today:

Date.today.strftime('%A')

If you're attempting to write your own calendar from scratch and want to write a function to do day lookup, you might want to check out Conway's Doomsday Algorithm, which is an interesting method for determining the day of the week on any given date. Otherwise the standard time class has a wday method which returns a number from 0-6 (0 is Sunday, 1 is Monday, etc).

We can use Time.now.utc.wday to get day of week without considering zone.

No need to use the Time class. date.cwday will return 1 for Monday, 2 for Tuesday etc.
