hebcal / gematriya

Simple Go implementation of gematriya, a system of writing numbers as Hebrew letters

gematriya

Package gematriya provides a system of writing numbers as Hebrew letters. Numerical values are represented using letters of the Hebrew alef-bet (alphabet).

Example

import (
  "fmt"
  "github.com/hebcal/gematriya"
)

str := gematriya.Gematriya(5749)
fmt.Println(str)
// Output: תשמ״ט

When specifying years of the Hebrew calendar in the present millennium, we omit the thousands (which is presently 5, ה). For example, the Hebrew year 5782 is written as 782 (תשפ״ב) rather than 5782 (ה׳תשפ״ב).

Value	Name	Letter
1	aleph	א
2	bet	ב
3	gimel	ג
4	dalet	ד
5	hay	ה
6	vav	ו
7	zayin	ז
8	khet	ח
9	tet	ט
10	yud	י
20	kaf	כ
30	lamed	ל
40	mem	מ
50	nun	נ
60	samech	ס
70	ayin	ע
80	pay	פ
90	tzadi	צ
100	kuf	ק
200	reish	ר
300	shin	ש
400	tav	ת

Note that the numbers 15 and 16 are treated specially, which if rendered as 10+5 or 10+6 would be a name of God, so they are normally written ט״ו (tet-vav, 9+6) and ט״ז (tet-zayin, 9+7).
