Here's more information on Yom Teruah; an excerpt from LightofMoshiach.org,
YHVH spoke to Moses, saying, "Speak to the sons of Israel, saying, ‘In the seventh month on the first of the month you shall have a rest, a reminder by blowing of trumpets, a holy convocation. ‘You shall not do any laborious work, but you shall present an offering by fire to YHVH.’" Leviticus 23:23-25

Yom Teruah begins a ten-day period leading up to the holiest day of YHVH's calendar, Yom Kippur -- the "Day Of Atonement." These ten days are called the 'Days of Awe' in modern Judaism. In fact, modern Judaism also includes the preceding month of Elul also as a time to prepare for the upcoming Fall moedim (appointed times). The sounding of the shofar on Yom Teruah is a wake-up blast -- a reminder that the time is near for the Day of Atonement. It is time to teshuvah (repent, turn back to YHVH). Traditionally, these ten days are ones of heart searching and self examination -- the shofar warns us we need to examine our lives and make amends with all those we have wronged in the previous year, and to ask forgiveness for any vows we may have broken. So a main theme of the Fall Holy Days is repentance.
