13 months
I want paid for the 4 weeks that go missing.
52 weeks in a year yet we are paid for 12 x 28 = 48 weeks.
52 - 48 = 4 week of unpaid work, a whole month.

There’s also 13 full moons every year over 28 days.
13 x 28 = 364 days.
Makes no sense to have 12 months where we have 13 moons of 28 days.
