Get each Wednesday for the rest of this year and all of next

wednesdays.coffee

dow = 3 # for Wednesday
this_year = today.getUTCFullYear()
next_year = this_year+1
wednesdays = []

days_in_month = (month, year) ->
  32 - new Date(year, month, 32).getDate()

year_number = this_year
while year_number <= next_year

  month_number = if year_number > this_year then 0 else today.getMonth()
  while month_number < 12

    d = 1
    end_of_month = days_in_month(month_number, year_number)
    while d <= end_of_month
      date = new Date year_number, month_number, d

      if date.getDay() is dow
        wednesdays.push date.toDateString()

      d++

    month_number++

  year_number++

wednesdays

The long way. Should just add 7 to the first known Wednesday 52 times...
