During the sixth month of Elisheva' s, Elizabeth, pregnancy Gavri-El, Gabriel, came to Mariam, Mary. Gavri-El told Mariam that Elizabeth was six months pregnant. This was six months after the priestly course of Abia which puts us at the end of the month Kislev (November-December). This would have been the time of Chanukah, the Festival of Lights, the rededication of the Temple.
Mariam is also told that she would be a vessel for the Messiah. This is confirmed when Mariam goes to Natseret, Nazareth, to the home of Elisheva and Zachar'yah a few days after Gavri-El announcement. I find it exciting that it's a three day trip to Elisheva. Can we say, "on the third day"?
Upon her arrival, John leaps for joy within Elisheva's, Elizabeth, womb. Elizabeth also, upon hearing Mariams voice, is filled with G-ds Holy Spirit. She says, "Blessed art thou among women, and blessed is the fruit of thy womb."
Therefore, on the third day, following Gabriels announcement to Mariam, Yeshua was in her womb. Yeshua was conceived at Chanukah, the Festival of Lights. It's only appropriate since He is the Light of the World, and he is responsible for the rededication of the present day temple of G-d, that is you and me.
You can read this account in Luke 1:26-55.
