TimezonePair is a free utility for distributed teams, remote workers, and anyone scheduling across time zones. Pick any two of 300 cities. Two live clocks tick in sync, a 24-hour horizon ribbon shows where your business hours overlap, and a single click downloads a .ics calendar invite or shares a URL that round-trips state. DST-aware, no sign-up, no tracking, no installs. 90,000 pre-rendered pair pages mean any combination is one URL away — Lisbon × Tokyo, New York × Sydney, anything.
