require 'date'
def weekdays(d1, d2)
count = 0
d1.upto(d2) do |date|
count += 1 if [1,2,3,4,5].include?(date.wday)
end
count
end
puts weekdays( Date.new(2006, 12, 1), Date.new(2007, 1, 16) )
A more useful twist might be to collect the weekdays and return an
array:
require 'date'
def weekdays(d1, d2)
_weekdays = []
d1.upto(d2) do |date|
_weekdays << date if [1,2,3,4,5].include?(date.wday)
end
_weekdays
end
puts weekdays( Date.new(2006, 12, 1), Date.new(2007, 1, 16) ).size
