The Manx ritual year ran on a calendar older than Christianity: Laa’l Breeshey (1 February), Laa Boaldyn (May Day), Tynwald Day / Midsummer Eve, Laa Luanys (Lammas), Hop-tu-Naa (31 October).

The Christian calendar laid its feasts on top without replacing the older dates. The Norse added their own layer. In 1753 the Gregorian calendar arrived, shifting everything by eleven days.

Build five parallel calendars for one year: the pre-Christian Manx year, the Christian liturgical year, the Norse/agricultural year, the Julian calendar, and the modern Gregorian calendar.

When you lay them side by side, you can see every culture’s calendar coexisting on the same island. No one replacing any other.
