1962 readings from the Bibles you already have

The app does not download a new lectionary. It computes the 1962 temporal day and pulls Epistle and Gospel from the Bibles bundled in the app — the ones you pick in Bible settings.

The calendar follows the Missale Meum / Divinum Officium ordo: Sundays, Ember weeks, octaves, Lenten ferias, transfers (All Souls off Sunday, Matthias in leap years, Immaculate Conception on an Advent Sunday).

Weekdays after Pentecost without a proper use the Sunday Mass (feria). Full local Polish propers are not in the general ordo.

This is hobby software with a real missal behind it. If a Sunday number is wrong, say so — we already fixed an off-by-one empty day.
