-- Easter-relative dates computed manually using Gregorian-algorithm output:
--   2026: Easter = 2026-04-05  (Karfreitag 04-03, Ostermontag 04-06,
--                               Christi Himmelfahrt 05-14,
--                               Pfingstsonntag 05-24, Pfingstmontag 05-25)
--   2027: Easter = 2027-03-28  (Karfreitag 03-26, Ostermontag 03-29,
--                               Christi Himmelfahrt 05-06,
--                               Pfingstsonntag 05-16, Pfingstmontag 05-17)
