Daylight World Clock

Find times that work for everyone with Daylight World Clock!

Stop doing time-zone math. Always know who's free, wherever they are.

See who's awake, who's not, and exactly when you're all free to talk. No account, no subscription, fully offline.

Add the places and people you care about — search 61,000+ cities in 230 countries, or jump there by airport code, 7,700+ of them, so LHR, JFK and ICN all work. Nowhere on the list? Drop a pin, name it, set its clock by hand.

Then see them four ways:

CLOCKS — the local time in each place, at a glance.
TIMELINE — everyone's day side by side, so you can see who's asleep and who's awake.
DAYLIGHT — see your whole day as a ring of real sky, from first light to dark, with everyone you care about placed around it.
WORLD — a 3D globe built from real satellite imagery: day, night, optional clouds, and time-zone bands (Pro).

Drag time around and every view changes at once. It's the fastest way to answer "If I call now, am I waking someone up?" or "Who'll be awake in 8 hours?"

FIND A TIME THAT WORKS
Set the hours each person is usually free, and Daylight lists the times that actually work for everyone. Pro unlocks the full list, plus copying a time in everyone's own local time, or sending it to your calendar.

ASK ANYONE WHEN THEY'RE FREE
Send someone a link. They mark their hours on a web page — no app, no account, nothing to install — and send back an answer that fills in by itself. Sending requests is Pro. Receiving one and answering it is free, for anyone, forever.

IT ALL RUNS ON YOUR DEVICE
Every city, every time zone, the globe imagery and the astronomy are in the app. No accounts, no analytics, no ads, nothing to sign in to. Daylight never uploads what you enter. Even a shared request travels inside the link itself — there's no database behind it, and nothing to leak.

WHAT'S FREE
Four places or people. All four views. Setting everyone's available hours. The three soonest times that work. And answering anyone's request.
