◊ how it works

Three pieces.
One screen. Nothing to install.

01
Two live clocks.
Synced every second. Tabular digits so nothing jitters. A sun-dial badge shows where each city sits in the day.
02
A 24-hour horizon.
Day and night painted on a single ribbon. A moss band glows where both cities are inside working hours.
03
One-click invite.
Scrub to a time, hit Add to calendar. A clean .ics file lands in your inbox — or share a URL with a teammate.
◊ every pair · every second

Meet at the meridian,
not in the margins.

No sign-up. No tracking. No apps to install. Just two live clocks, a horizon that tells you when to meet, and a link your teammates can open in a second.

lat 38.72° N
