it's april 28th, and it is a beautiful liturgy with really ornate palm shapes that people (often the children) make on the saturday. try to get to the saturday as well, there is a special liturgy then too.
then there is a break for lunch (or people bring packed lunch - vegan, remember as it's still lent on the old calendar!), then the holy week services (at least 2 every day) start on sunday afternoon.
the first service is around 2 hours and involves lovely prayers and prostrations and the singing of a funky tune called 'thoak ta te gom', which is 'yours is the power and the glory and the blessing and the majesty', usually sung in coptic, with the last chorus (refrain) in both arabic and the local language.
it is one of my favourite hymns, as it has a funky tune and is repeated many times, so you eventually can learn it (at least by the end of holy week).
may God bless your holy week, all catholics, armenian orthodox and others commemorating it around this time.
as for sleeping in, there are 2 'cures' to be used at the same time:
1. form a habit of going to bed early every day.
2. buy an alarm clock (they are modern inventions that combine the clever marking of time, with a little device that makes a noise at a set time. if you haven't seen one before, try google or ebay).
