The name Zillethai in Hebrew letters is צלתי. 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.
צלתי
In short
Your name in Hebrew letters is צלתי. A Tanakh name: the name of two Israelites (first in 1 Chronicles 8:20; 2 mentions in the Tanakh). Meaning, per Strong’s dictionary (1890): “shady”. Adding up the numbers of its letters gives 530 — the same as the Torah word שכיר, “hired worker”. That number points to Torah page 176 of 354 — in the portion Tzav. What that portion is about: The fire on the altar is never to go out; the priests' portion; the seven days of consecration of Aaron and his sons. The verse that begins with the first letter of your name and ends with the last is 2 Samuel 23:28. Each of these steps is laid out below with its sources. Every figure can be checked by hand.
You wrote “Zillethai” — this exact spelling is what was calculated: צלתי. 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 צלתי gives 530.
530
The number 530 is the Torah word שכיר — «hired worker» (Exodus 12:45).
which HaShem commanded to be given them of the children of Israel, in the day that they were anointed. It is a due for ever throughout their generations.
This is from the portion Tzav. What it is about: The fire on the altar is never to go out; the priests' portion; the seven days of consecration of Aaron and his sons.
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) — 530. A Torah word with the same number is שכיר — “hired worker” (Exodus 12:45).
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) — 62. A Torah word with the same number is בין — “between” (Genesis 1:4).
Cumulative: a letter plus all letters before it (mispar kidmi) — 2150.
Squares of the letter values (mispar perati) — 169100.
Building: the sum grows with each letter (mispar bone’eh) — 1260.
The letters that come out are הכאמ — not a word that stands in the Pentateuch. Atbash: letters mirrored, alef for tav, bet for shin, and the number of the resulting word — 66. A Torah word with the same number is כמו — “like, as” (Genesis 19:15).
Filling: the names of the letters are counted — alef, bet, gimel… (milui) — 604. A Torah word with the same number is צדקתי — “my righteousness” (Genesis 30:33).
The number 530 appears in the classical books 6 times across 4 works. The earliest mention is מדרש לפירושים (~1450?).

The number of the day, every morning
Every date has a number too. Once a year it will match the number of your name — 530. The channel posts one number a day, one verse and the Torah page it lands on. Nothing after it, no mailing list.

The name צלתי 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
The Pentateuch has no verse that begins with צ and ends with י. The custom allows the whole Tanakh — the Prophets and the Writings have 11 such verses. The first of them is 2 Samuel 23:28:
The name צלתי has no such day. The numbers of the dates in a year cover 326 values out of 940, and 530 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.
