Orbit

Orbit is a world clock built around one question: "When it's 3 PM here, what time is it everywhere else?" Instead of reading a static list of clocks and doing the math in your head, Orbit lets you move time itself — and watch every city answer at once. TIMELINE MODE Drag the slider to travel up to 24 hours forward or back, in 15-minute steps. Every city's time, date, and day/night indicator shifts in sync. Quick −1d / −1h / +1h / +1d buttons for precise jumps, and one tap on "Now" snaps you back to live time. CALENDAR MODE Tap "Plan a date & time" and the calendar unfolds right under the slider — nothing jumps, nothing rearranges. Plan across time zones like a sentence: "When it's 3:15 PM in Seoul…" Pick a city, a time, and a date, and instantly see the local time, date, and day of the week for every city on your list. Perfect for scheduling calls, flights, launches, or just knowing when to say happy birthday. "Back to Now" brings you to the present without closing the planner. YOUR CITIES Search over 370 major world cities — plus the full timezone database — by city, state, or country. Cities that share a timezone are all in there: San Francisco, Busan, Boulder, Beijing. You can also type it the way you say it: NYC, Bombay, Saigon, or a zone code like EST or PST. Each row shows the local time, full date, sunrise/day/sunset/night indicator, offset from your home city, and a +1/−1 badge when it's already tomorrow (or still yesterday) there. Your list is saved and syncs with your Chrome profile. SUMMER TIME, WITHOUT SURPRISES One tap on the info button lists every upcoming daylight-saving change across your cities — grouped by date, and translated into what actually matters: "Nov 1 — Los Angeles, New York: summer time ends, clocks go back 1 hour." PRIVATE BY DESIGN Orbit makes zero network requests. No accounts, no analytics, no data collection — your city list is stored only in your browser. The only permission it asks for is storage, to remember your cities. Designed with a clean, glass-like interface in both light and dark — it follows your system theme, or you can pin either one with the toggle.
