There is some evidence they did, namely what’s now called Michaelmass (the Feast of Michael and all Angels), which would have been (as Sept 29 by modern calenders) the start of the Feast of Tabernacles in the year Christ was born (according to one reckoning of the year evidence – not AD 1).
There’s a fascinating tale (quite epic in some extended versions) passed down among non-Christian rabbis in late antiquity and the medieval period, as a sort of myth to account for various details about Christianity that they found annoying – about how Simon Peter was really an orthodox Jewish sage who voluntarily sacrificed his reputation to lead the Nazarenes to stop going to Jewish feasts on one hand and to treat Jews with self-sacrificial kindness on the other hand – and one of the points the non-Christian Jews were “explaining” this way is why Christians celebrated the birth and circumcision of “the Crucified” instead of Tabernacles and Atonement.
What’s especially curious about this part of the legend is that the earliest we can track it back is around the 7th century, long after they should have been coming up with explanations about why Christians celebrate specifically on Dec 25th (and/or early January) – which a connection to pagan festivals would have provided some hot ammunition! Also, this legendary explanation connects the abandonment of Tabernacles/Atonement to the abandonment of Passover and Pentacost, but those two explanations are connected directly to substitutions which are celebrated at the same times as before (more or less, since the Pascha / Easter isn’t celebrated exactly on Passover full moon calculations anymore but on the nearest Friday-Saturday-Sunday block afterward; this also naturally affecting Whitsunday, which many Protestants have dropped altogether now.)
The implication is that the Jews were remembering a time when Christians started celebrating events of Christ’s birth, death, resurrection, and ascension, at around the same time as Passover, Pentacost, and Tabernacles: a point they thought Simon Peter taught the Nazarenes but which they had to explain because, at least as far down as the 7th century, at least one of Peter’s liturgical hymns that he wrote after becoming a ‘Nazarene’ was still being sung in synagogues!
But yeah, the Christian evidence of celebrating Christ’s birth before Constantine in the 300s is spotty at best. That silence is hard to explain in any case; it isn’t like GosMatt and GosLuke weren’t popularly accepted as canon before then. (GosMatt was the most popular Gospel by far, on the contrary!)
