In Númenor, there were three annual celebrations of a religious character:
- Erukyermë at the beginning of spring, the prayer for a good year
- Erulaitalë in the middle of summer, the prayer for a good harvest
- Eruhantalë in the autumn, the thanksgiving for a good harvest
Collectively these were known as the Three Prayers.
Since Erukyermë marked the beginning of a new year, this points to the existence of a separate calendar for religious purposes, beginning at vernal equinox. For civil matters the Edain started the year in the middle of winter, just after Yule, a tradition attested as far back as the First Age.
