The noun meaning “a year’s absence granted to researchers” (originally one year in seven, to university professors) is from 1934, short for sabbatical year, etc., which was recorded by 1886 (the thing itself is attested from 1880, at Harvard), a term perhaps suggested by the sabbatical year (1590s) in Mosaic law, the seventh year, in which land was to remain untilled and non-foreign debtors and slaves released.
Online Etymology Dictionary
These days a sabbatical is rarely a year but is still used to indicate a time away from work, sometimes paid and sometimes otherwise (and when not, it’s usually referred to as a career break).
I’m fortunate that at Automattic, every 5 years, we get a 3 month, fully-paid sabbatical. And mine is now due.
When to go and what shall I do?
