About GlobeTime Calculator

GlobeTime Calculator is a free set of time calculators for two kinds of questions: how much time did I work? and what time is it over there?

It is built and maintained by Novarte AI, a small web studio in Salt Lake City, Utah.

How the numbers are made

• Every calculation runs in your browser. Nothing you type is sent to a server.
• Time zone and daylight saving rules come from the IANA time zone database built into your browser and, for the tables on each page, from the same database at build time.
• Pay and overtime results are estimates for planning. Payroll rules vary by employer and state.
