Christos Anesti! Or if you prefer, Christos Voskres!
It is Orthodox Easter (Pascha), and this comes with prayers for our Orthodox Christian sisters and brothers and thanksgiving for their witness.
Ormonde Plater has a lovely post on this occasion, with music, so I'll just send you there. Thank you, Ormonde.
