Is the teaching that Christ will return on the Feast of Trumpets biblical?

Many "messianics" and "torah observant christians" are teaching that the second coming of christ will be on yom teruah, the feast of trumpets  and they also teach that we must observe all these feasts in order to "rehearse" for it.  They literally believe He will come on the "hidden day" as determined by the rabbis in Israel who are supposedly watching the phases of the moon.
