How is this different from Genna?
Genna, Ethiopian Christmas, was 7 January, Tahsas 29. Timkat is twelve days later, Tir 11, Tuesday 19 January 2027. The tabots are carried out and the water is blessed. The night before is Ketera. Churches that keep a Julian Christmas also used 7 January, and that liturgy is not Timkat.
The months up to Genna are on the Hidar and Tahsas page. The Timkat page is the water, and it takes a listing only when a parish or a kitchen is already named.
