The name Tarshish in Hebrew letters is תרשיש. 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.
תרשיש
In short
Your name in Hebrew letters is תרשיש. A Tanakh name: a Mediterranean place; also a Persian and an Israelite (first in Genesis 10:4; 23 mentions in the Tanakh). Adding up the numbers of its letters gives 1210 — the same as the Torah word תרשיש, “beryl gemstone”. That number points to Torah page 148 of 354 — in the portion Ki Tisa. What that portion is about: The half-shekel for the census; the golden calf and the broken tablets; the thirteen attributes of mercy; the second tablets. The verse that begins with the first letter of your name and ends with the last is Psalms 21:10. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Tarshish” — this exact spelling is what was calculated: תרשיש. 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 תרשיש gives 1210.
1210
The number 1210 is the Torah word תרשיש — «beryl gemstone» (Exodus 28:20).
And HaShem repented of the evil which He said He would do unto His people.
This is from the portion Ki Tisa. What it is about: The half-shekel for the census; the golden calf and the broken tablets; the thirteen attributes of mercy; the second tablets.
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) — 1210. A Torah word with the same number is תרשיש — “beryl gemstone” (Exodus 28:20).
Reduced, each letter to one digit (mispar katan) — 13. A Torah word with the same number is אחד — “one” (Genesis 1:5).
Ordinal: alef 1, bet 2 … tav 22 (mispar siduri) — 94. A Torah word with the same number is צד — “side” (Genesis 6:16).
Cumulative: a letter plus all letters before it (mispar kidmi) — 4535.
Squares of the letter values (mispar perati) — 380100.
Building: the sum grows with each letter (mispar bone’eh) — 4020.
The letters that come out are אגבמב — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 48. A Torah word with the same number is יובל — “ram's horn, jubilee” (Exodus 19:13).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 1656.

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 1210. 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. תרשיש has 5 letters: ת Tav, ר Resh, ש Shin, י Yod, ש Shin. The first letter is Tav, the last is Shin.
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 תרשיש appears in the Torah as a word 2 times. The first time is Génesis 10:4. Another 1 time it stands with prefixes — “and”, “in”, “the”.
The verse of your name
The Pentateuch has no verse that begins with ת and ends with ש. The custom allows the whole Tanakh — the Prophets and the Writings have 3 such verses. The first of them is Psalms 21:10:
The name תרשיש has no such day. The numbers of the dates in a year cover 326 values out of 940, and 1210 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.
