The year 5720 תש״כ
5720 in the Jewish calendar is written ה׳תש״כ — the ה is the 5,000 years, and the letters after it are the 720 since. Written on its own, as it is on nearly every page that carries a date, the year is תש״כ, and those letters add to 720.
The letters, and what each is worth
400 + 300 + 20 = 720, computed by the same engine that computes every value on this site, over the same consonantal letters.
Why the five thousand is missing
The full form is ה׳תש״כ: the first letter carries the 5,000. In ordinary use it is left off and the year is written תש״כ followed by לפ״ק — lifrat katan, “by the minor reckoning”, which is the writer saying out loud that the thousands have been dropped. It is a habit of writing and not a claim about the number: the year is 5,720, and 720 is what its letters spell.
What the letters spell
No word of the twenty-four books is written תשכ — nor is any word written with these letters in any other order. The year’s letters are a numeral here, not a word, and this page will not make one out of them.
720 in the Tanakh
38 words, 841 phrases and 2 whole verses carry the value 720 under the standard method — 879 matches in all.
The letters of a Jewish year are a numeral, and this page treats them as one. Every value here is the engine’s, computed on the consonantal letters at the moment the page is served, and every count is read from the Westminster Leningrad Codex. Nothing on this page is a prediction.
