The name Josiah in Hebrew letters is יאשיהו. 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.
יאשיהו
In short
Your name in Hebrew letters is יאשיהו. A Tanakh name: the name of two Israelites (first in 1 Kings 13:2; 53 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “founded of God”. Adding up the numbers of its letters gives 332 — the same as the Torah word לבש, “to put on, clothe”. That number points to Torah page 332 of 354 — in the portion Ki Teitzei. What that portion is about: “When you go out”: seventy-four commandments — the bird's nest, honest weights, divorce, remembering Amalek. The verse that begins with the first letter of your name and ends with the last is Genesis 9:27. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Josiah” — this exact spelling is what was calculated: יאשיהו. 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 יאשיהו gives 332.
332
The number 332 is the Torah word לבש — «to put on, clothe» (Genesis 3:21).
then they shall bring out the damsel to the door of her father's house, and the men of her city shall stone her with stones that she die; because she hath wrought a wanton deed in Israel, to play the harlot in her father's house; so shalt thou put away the evil from the midst of thee.
This is from the portion Ki Teitzei. What it is about: “When you go out”: seventy-four commandments — the bird's nest, honest weights, divorce, remembering Amalek.
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) — 332. A Torah word with the same number is לבש — “to put on, clothe” (Genesis 3:21).
Reduced, each letter to one digit (mispar katan) — 17. A Torah word with the same number is טוב — “good” (Genesis 1:4).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 53. A Torah word with the same number is אבן — “stone” (Genesis 2:12).
Cumulative: a letter plus all letters before it (mispar kidmi) — 1242.
Squares of the letter values (mispar perati) — 90262.
Building: the sum grows with each letter (mispar bone’eh) — 1311.
The letters that come out are מתבמצפ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 652. A Torah word with the same number is מרבית — “increase, profit” (Leviticus 25:37).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 529. A Torah word with the same number is העתדים — “the male goats” (Genesis 31:10).
The number 332 appears in the classical books 5 times across 3 works. The earliest mention is מגלה עמוקות (~1637).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 332. 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. יאשיהו has 6 letters: י Yod, א Alef, ש Shin, י Yod, ה He, ו Vav. The first letter is Yod, the last is Vav.
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 יאשיהו 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 יאשיהו these are י and ו. The Pentateuch has 7 such verses. The first of them is Genesis 9:27:
יפת אלהים ליפת וישכן באהלי שם ויהי כנען עבד למו
This is from the portion Noach. What it is about: The flood and the ark; the rainbow as a sign of the covenant; the tower of Babel; ten generations from Noah to Abraham.
Any name written in Hebrew letters is a number: יאשיהו = 332. And every date has a number of its own. There is a day in the year when the two coincide.
«then they shall bring out the damsel to the door of her father's house, and the men of her city shall stone her with stones that she die; because she hath wrought a wanton deed in Israel, to play the harlot in her father's house; so shalt thou put away the evil from the midst of thee.»
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.
