Method: Timely::WeekDays#initialize

Defined in:
lib/timely/week_days.rb

#initialize(weekdays) ⇒ WeekDays

Create a new Weekdays object weekdays can be in three formats integer representing binary string

e.g. 1 = Sun, 2 = Mon, 3 = Sun + Mon, etc.

hash with symbol keys for :sun, :mon, … with true/false values

e.g. {:sun => true, :tue => true} is Sunday and Tuesday
