Today marks the Spring Equinox (in South Africa, anyway). It is also, in the Gregorian Calendar, the Feast of the Conception of St John the Baptist. And, though it doesn’t coincide exactly this year, it is at about this time that Jews celebrate Rosh Hashanah, the new year, the birthday of the universe (Orthodox Christians celebrate the new year and creation on 1 September).
The Conception of St John the Baptist, which roughly coincides with the birthday of the universe in Jewish tradition, also, for Christians marks the beginning of God’s new creation, which we are reminded of in the southern hemisphere because it’s the middle of spring. It’s also symbolic because henceforth the days are longer than the nights, reminding us of the words of the Holy Forerunner and Baptist John that the light shines in the darkness and the darkness could not overcome it (John 1:5).
Six months after the conception of St John the Baptist and Rosh Hashanah, on 25 March, the angel Gabriel came to Mary, and told her she would be the Theotokos, the birth giver of God (Luke 1:26). Mary went to stay with Elizabeth, the mother of St John the Baptist, until he was born, which the Church celebrates on 24 June (Luke 1:56f), and then we celebrate the birth of our Lord and God and Saviour Jesus Christ on 25 December.
There are all sorts of speculations about the date on which Jesus was born, and what I’ve written above is my speculation, which is probably no more valid than any of the others, but I don’t think it is any less valid. In this matter there is no proof, only vigorous assertion, which is not quite the same thing.
Troparion — Tone 4
Rejoice, O barren one, who formerly did not bear a child
for you have conceived the Lamp of the Sun
who is to illumine the whole universe darkened by blindness
Rejoice, O Zachariah
and cry out with boldness:
“The prophet of the Most High desires to be born!”
