Blessed Feast to you! My husband and I married before we converted to the Orthodox Faith, and our wedding anniversary falls during Dormition fast, on August 9th. This year we are celebrating 7 years of marriage. On our fourth anniversary, my grandfather departed this life, so on that day we also remember him--Memory Eternal! It happens that I was born on my grandparent's wedding anniversary, which I think forms an interesting circle. This morning during Divine Liturgy, I was struck by the Troparion of the Feast and how it similarly juxtaposes birth and death.
Theotokos and St. John the Forerunner. In fact, we even commemorate the conception of these Saints. However, for most saints, the date of their repose is the primary date on which the they are honored.
