The days of this holiday cannot be known before they happen. Only by the sighting of the new moon starts this 'Moed' (God's day of appointment).

The words Rosh HaShana in this context do not appear in the Torah. They mean head of the year.

This day commemorates the first and only time that the "Trump of יְהוָה " was used. Yet it will be used at the "Last Trump" one of these years.

Exodus 19

וַיְהִי בַיּוֹם הַשְּׁלִישִׁי בִּהְיֹת הַבֹּקֶר וַיְהִי קֹלֹת וּבְרָקִים וְעָנָן כָּבֵד עַל־הָהָר וְקֹל שֹׁפָר חָזָק מְאֹד וַיֶּחֱרַד כָּל־הָעָם אֲשֶׁר בַּמַּחֲנֶה:
And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud; so that all the people that was in the camp trembled.

וַיּוֹצֵא מֹשֶׁה אֶת־הָעָם לִקְרַאת הָאֱלֹהִים מִן־הַמַּחֲנֶה וַיִּתְיַצְּבוּ בְּתַחְתִּית הָהָר :
And Moses brought forth the people out of the camp to meet with God; and they stood at the nether part of the mount.

וְהַר סִינַי עָשַׁן כֻּלּוֹ מִפְּנֵי אֲשֶׁר יָרַד עָלָיו יְהוָה בָּאֵשׁ וַיַּעַל עֲשָׁנוֹ כְּעֶשֶׁן הַכִּבְשָׁן וַיֶּחֱרַד כָּל־הָהָר מְאֹד:
And mount Sinai was altogether on a smoke, because the LORD descended upon it in fire: and the smoke thereof ascended as the smoke of a furnace, and the whole mount quaked greatly.

You will note that the word God is the same for any god 'eloa' or 'elohim'

But the word that is translated Lord is no 'lord' at all but the actual name of the almighty. (seen below clearly written in gold).

The earth will one day quake at the sound of the וְקֹל שֹׁפָר חָזָק of God. The dead will be raised. This is our hope.

Happy Rosh HaShana

from the middle of Yom Teruah (which is what it used to be called.)

Thanks for taking the time to read.
all photos were taken by me.

For the next 21 hours, you can observe people celebrating Yom Teruah live via this link, which is a live web cam in Jerusalem. The celebration will terminate with the "last trump" around 21 hours from this post.
