About

DatenTime is a small utility site for local times, timezone comparisons, and calendar-aware date calculations. City and country clocks use IANA timezone identifiers such as Europe/London and America/New_York. The site does not treat a country as having one time when it uses several zones.

Date tools add months using calendar logic: 31 January plus one month becomes the last day of February, not a fictional 31 February and not a fixed 30-day month. Relative-date landing pages are limited to common search phrases so the site does not generate an infinite set of URLs.
