How can I calculate the day of the week of a date in ruby?
I have used this because I hated to go to the Date docs to look up the strftime syntax, not finding it there and having to remember it is in the Time docs.
require 'date'class Date def dayname DAYNAMES[self.wday] end def abbr_dayname ABBR_DAYNAMES[self.wday] endendtoday = Date.todayputs today.daynameputs today.abbr_dayname
Take a look at the Date class reference. Once you have a date object, you can simply do dateObj.strftime('%A')
for the full day, or dateObj.strftime('%a')
for the abbreviated day. You can also use dateObj.wday
for the integer value of the day of the week, and use it as you see fit.
