The name Tahath in Hebrew letters is תחת. Below: how its number adds up, which page of the Torah it falls on and what verse stands there. Everything is computed, nothing is guessed.
תחת
In short
Your name in Hebrew letters is תחת. A Tanakh name: the name of three Israelites (first in Numbers 33:26; 6 mentions in the Tanakh). Adding up the numbers of its letters gives 808 — the same as the Torah word תחת, “under, beneath”. That number points to Torah page 100 of 354 — in the portion Vaera. What that portion is about: “And I appeared”: the promise of redemption in four expressions; the first seven plagues, from blood to hail. The verse that begins with the first letter of your name and ends with the last is Exodus 15:16. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Tahath” — this exact spelling is what was calculated: תחת. A name from the Tanakh — its Tanakh spelling is used. If your name is spelled differently, correct the Hebrew spelling and the report is recomputed.
Adding up the letters of the name תחת gives 808.
808
The number 808 is the Torah word תחת — «under, beneath» (Genesis 1:7).
And I will bring you in unto the land, concerning which I lifted up My hand to give it to Abraham, to Isaac, and to Jacob; and I will give it you for a heritage: I am HaShem.'
This is from the portion Vaera. What it is about: “And I appeared”: the promise of redemption in four expressions; the first seven plagues, from blood to hail.
Other ways of counting
The tradition counts the same name in several ways. The main one is above: each letter is its number. The other eight are old and checkable too; each gives its own number, and many of them have a Torah word with the same number.
Final letters as 500–900 (mispar gadol) — 808. A Torah word with the same number is תחת — “under, beneath” (Genesis 1:7).
Reduced, each letter to one digit (mispar katan) — 16. A Torah word with the same number is אחז — “to seize” (Genesis 22:13).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 52. A Torah word with the same number is בן — “son” (Genesis 3:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 3026.
Squares of the letter values (mispar perati) — 320064.
Building: the sum grows with each letter (mispar bone’eh) — 1616.
The letters that come out are אסא — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 62. A Torah word with the same number is בין — “between” (Genesis 1:4).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1230.
The number 808 appears in the classical books 1 time across 1 work. The earliest mention is תורת העולה (~1570).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 808. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.
Hebrew is written from right to left. תחת has 3 letters: ת Tav, ח Chet, ת Tav. The first letter is Tav, the last is Tav.
For an engraving, a sign or a tattoo, show the spelling to someone who reads Hebrew: transliterating a name is a choice, not the only option.
The name תחת appears in the Torah as a word 90 times. The first time is Genesis 1:7. Another 28 times it stands with prefixes — “and”, “in”, “the”.
The verse of your name
There is a custom: at the end of the prayer one says a Torah verse that begins with the first letter of one's name and ends with its last. For תחת these are ת and ת. The Pentateuch has exactly one such verse — Exodus 15:16:
תפל עליהם אימתה ופחד בגדל זרועך ידמו כאבן עד יעבר עמך ה׳ עד יעבר עם זו קנית
This is from the portion Beshalach. What it is about: The parting of the sea and the song of Moses and Miriam; manna and quail; water from the rock; the war with Amalek.
The name תחת has no such day. The numbers of the dates in a year cover 326 values out of 940, and 808 is not among them. Half of all names are like this — neither good nor bad, just a fact of counting.
Add a date of birth and the verse of meeting from that week's portion is added to the reading.
Each Hebrew letter has a number; a word's number is their sum (alef 1 … tav 400). The page is the remainder modulo 354: the Torah divided into 354 pages of 861 letters, as the lunar year has 354 days. Everything can be checked by hand.
