The new moon (first sliver) was sighted on the evening of March 30, 2025 by several witnesses in the United States and other parts of the world. This makes March 31, 2025 Rosh Hashanah (First day of the new year). This time is important because it sets the time line for the Spring Moedim and Fall Moedim throughout the year.
Last year had 13 months, which more than likely would indicate that we will only have 12 months in this year. The Bible never provides an exact number of months for the biblical year. What it does provide is the method to begin the year and count each subsequent month. The Bible confirms that the first month of the biblical year is called "Abib" pronounced "Aveev." Deuteronomy 16:1 TS2009 states, "Guard the new moon of Aḇiḇ, and perform the Pěsaḥa to יהוה your Elohim, for in the new moon of Aḇiḇ יהוה your Elohim brought you out of Mitsrayim by night."
There are people who keep the Moedim on different dates for corporate reasons as I have been told. Is this okay to do? Absolutely not! Elohim commanded these times according to his calendar, not one we create. These people who do not keep Elohim's time line disturb the order and confound all the days, the holy with the unclean and the unclean day with the holy. They will go wrong as to the months and Sabbaths and Feasts and Jubilees.
Jubilees 6:
37 For this reason the years will come upon them when they will disturb (the order), and make an abominable (day) the day of testimony, and an unclean day a feast day, and they will confound all the days, the kodesh with the unclean, and the unclean day with the kodesh; for they will go wrong as to the months and Shabbats and feasts and jubilees.
38 For this reason I command and testify to you that you may testify to them; for after your death your children will disturb them, so that they will not make the year three hundred and sixty-four days only, and for this reason they will go wrong as to the new months and seasons and Shabbats and festivals, and they will eat all kinds of blood with all kinds of flesh.
