Meaning
Current, and reflecting the most recent available information, developments, or standards.
It’s used for anything from records and software to knowledge and fashion — whatever has kept pace with the latest changes rather than lagging behind.
Origin
The phrase comes from bookkeeping practice, where a ledger described as “kept up to date” was accurately recorded and balanced through the present day, with no outstanding entries left unrecorded. Its opposite, “out of date,” meaning no longer current or fashionable, is actually the older of the pair, attested in English from around 1600; “up to date” arose later as the natural counterpart, extending from strict bookkeeping accuracy to a much broader sense of being current with information, technology, or trends in general.
