The name Shai in Hebrew letters is שי. 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.
שי
In short
Your name in Hebrew letters is שי. A Tanakh word: “gift” (first in Isaiah 18:7). Adding up the numbers of its letters gives 310 — the same as the Torah word חשב, “to reckon, think”. That number points to Torah page 310 of 354 — in the portion Eikev. What that portion is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema. The verse that begins with the first letter of your name and ends with the last is Exodus 12:15. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Shai” — this exact spelling is what was calculated: שי. 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 שי gives 310.
310
The number 310 is the Torah word חשב — «to reckon, think» (Genesis 15:6).
And HaShem delivered unto me the two tables of stone written with the finger of G-d; and on them was written according to all the words, which HaShem spoke with you in the mount out of the midst of the fire in the day of the assembly.
This is from the portion Eikev. What it is about: “Because you will heed”: the land of seven fruits; the blessing after meals; manna as a test; the second paragraph of the Shema.
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) — 310. A Torah word with the same number is חשב — “to reckon, think” (Genesis 15:6).
Reduced, each letter to one digit (mispar katan) — 4. A Torah word with the same number is אבא — “I will come” (Genesis 33:14).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 31. A Torah word with the same number is אל — “to, toward” (Genesis 1:9).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1150.
Squares of the letter values (mispar perati) — 90100.
Building: the sum grows with each letter (mispar bone’eh) — 610. A Torah word with the same number is יתר — “to remain over” (Genesis 30:36).
The letters that come out are במ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 42. A Torah word with the same number is חדל — “to cease” (Genesis 11:8).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 380. A Torah word with the same number is מצרים — “Mizraim, Egypt” (Genesis 10:6).
The number 310 appears in the classical books 27 times across 16 works. The earliest mention is בעל הטורים על התורה (~1300).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 310. 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. שי has 2 letters: ש Shin, י Yod. The first letter is Shin, 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 שי does not stand as a word in the Pentateuch — as with most names, including many Tanakh names from the later books.
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 שי these are ש and י. The Pentateuch has 2 such verses. The first of them is Exodus 12:15:
שבעת ימים מצות תאכלו אך ביום הראשון תשביתו שאר מבתיכם כי כל אכל חמץ ונכרתה הנפש ההוא מישראל מיום הראשן עד יום השבעי
This is from the portion Bo. What it is about: Locusts, darkness and the death of the firstborn; the Passover lamb; the exodus from Egypt; the commandment of tefillin.
A verse whose whole sum equals your name
גד גדוד יגודנו והוא יגד עקב
Genesis 49:19 · 22 letters in the verse
All the letters of this verse add up to 310 — exactly your name's number. The Pentateuch has 5,853 verses, and only 200 of them fall below 1000. Of the 2,980 names in our index, 80 match this way — about one name in thirty-seven.
The name שי has no such day. The numbers of the dates in a year cover 326 values out of 940, and 310 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.
