Calculation

The template then gives j, the day of the month, as calculated by the following formulae.

j = 7×n − 6 + (w − w₁) mod 7 (for positive n)

j = t + 7×(n + 1) − (w_t − w) mod 7 (for negative n)

Where t is the last day of the month, w_t is the non-ISO weekday number of the last day of the month, w₁ is the non-ISO weekday number of the first day of the month and n and w are as defined above.
