Good uses for a clock with seconds
- Meetings and standups — keep time-boxed turns honest.
- Classrooms — a visible reference for tests, breaks and transitions.
- Recording and streaming — a precise on-screen clock for cues.
- Science and cooking — quick reference when you need the seconds hand.
12-hour vs 24-hour
Most of the world uses 24-hour time (00:00–23:59). The US, Canada, Australia and a few others default to 12-hour with AM/PM. Pick whichever your team reads faster — Timecade remembers the choice across the whole app.
