"Fall Feasts of the Lord - Prophecies"
Jesus, the greek name adopted by the believers in the area of Capernaum and northern, is a translation with no hebrew origin. Y-ah-ho-shu-ah is sort of the way you would speak the name He had from Mary and Joseph- or our version of it, 'Joshua'. 'Jo' and 'Jea' and 'Joh' is a common hebrew name-syllable, and is directly related to 'Y-', aka, 'Yah'. It's pretty common in english, french, spanish, etc, and usually mean's 'God's ', 'God is...', etc. In the case of Yahoshua, it pretty literally means '(My) God is salvation / God saves'. 'Yah' is the foreshortened nickname for the most Holy name, 'Y-ah-owv-ah'. It's technically right when folk say 'God's name is unpronounceable', but about as stupid as saying 'God's name is ineffable'- it was meant to be spoken, loved, and completely respected.
Yahoshua's birthday actuallly coincided very well with the fall feasts of Israel- the festival of trumpets and first fruits, where the shepherds were watching the sheep on the hills. The lambing is generally in the spring season in Israel, and the guarding has to happen at night when wolves, jackals and prey animals are most likely to creep out of the foothills to have some dinner. The lambs are still most vulnerable until mid-winter, where they are good and strengthened on the summer and fall grasses. You can calculate John the baptist's and Jesus' birthdays very well though by the details given in the gospels.
The celebration of Yule/December 25th stems from the worship of Talmus, son of Ishtar, an empress in the old kingdom of Babylon/sumeria. You'll have to do some proper reading to track that down, but the story of the worship of Ishtar/Easter is fascinating. It's... very prevelent in our current traditions, but just named differently. It's also one of the reasons that a clear understanding of the scriptures, as close to the original language as possible, is so enriching.
