The name Ittai in Hebrew letters is אתי. 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.
אתי
In short
Your name in Hebrew letters is אתי. A Tanakh name: a Gittite and an Israelite (first in 2 Samuel 15:19; 9 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “near”. Adding up the numbers of its letters gives 411 — the same as the Torah word שלמיאל, “Shelumiel, chief of Simeon”. That number points to Torah page 57 of 354 — in the portion Vayishlach. What that portion is about: Wrestling with the angel and the name Israel; the meeting with Esau; Dinah in Shechem; the birth of Benjamin and Rachel's death. The verse that begins with the first letter of your name and ends with the last is Genesis 15:19. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Ittai” — this exact spelling is what was calculated: אתי. 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 אתי gives 411.
411
The number 411 is the Torah word שלמיאל — «Shelumiel, chief of Simeon» (Numbers 1:6).
And Jacob lifted up his eyes and looked, and, behold, Esau came, and with him four hundred men. And he divided the children unto Leah, and unto Rachel, and unto the two handmaids.
This is from the portion Vayishlach. What it is about: Wrestling with the angel and the name Israel; the meeting with Esau; Dinah in Shechem; the birth of Benjamin and Rachel's death.
The same number, 411, is given by these Tanakh names:
Elisha אלישע
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) — 411. A Torah word with the same number is שלמיאל — “Shelumiel, chief of Simeon” (Numbers 1:6).
Reduced, each letter to one digit (mispar katan) — 6. A Torah word with the same number is בד — “alone, apart” (Genesis 2:18).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 33. A Torah word with the same number is גל — “heap of stones” (Genesis 31:46).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1551.
Squares of the letter values (mispar perati) — 160101.
Building: the sum grows with each letter (mispar bone’eh) — 813. A Torah word with the same number is התחת — “am I in place of” (Genesis 30:2).
The letters that come out are תאמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 441. A Torah word with the same number is אמת — “truth, faithfulness” (Genesis 24:27).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 537. A Torah word with the same number is מטבעתיו — “by its rings” (Exodus 28:28).
The number 411 appears in the classical books 11 times across 8 works. The earliest mention is ספר קרניים (~1400).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 411. 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. אתי has 3 letters: א Alef, ת Tav, י Yod. The first letter is Alef, the last is Yod.
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 אתי appears in the Torah as a word 42 times. The first time is Genesis 4:14.
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 אתי these are א and י. The Pentateuch has 17 such verses. The first of them is Genesis 15:19:
את הקיני ואת הקנזי ואת הקדמני
This is from the portion Lech Lecha. What it is about: “Go forth”: Abraham leaves Haran; the promise of land and offspring; the covenant between the pieces; circumcision.
The name אתי has no such day. The numbers of the dates in a year cover 326 values out of 940, and 411 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.
