Distributed product teams
Standups, design reviews and launch calls across three continents, without the spreadsheet of offsets.
Time zones, side by side
Add everyone's city and working hours. Zoneline lines up each day, finds the three best windows to meet, and turns the whole view into one link you can send.
Free to use · No sign-up · Your team lives in the link, not on our servers
No one here yet.
Add the first person — their city and working hours — and Zoneline will start lining up the day.
How it works
Each person gets a row tinted from dawn to night, so you can see who's starting, who's wrapping up, and who should be asleep.
We rank the stretches where working hours overlap. When nothing fits everyone, you get the least-bad hour and exactly who is stretching for it.
Real IANA time zones, straight from your browser. Pick any date to see 23- and 25-hour days, and the weeks when the usual gap shifts.
Names, cities, hours and the date all travel in the URL. Paste it in a chat or an email and it opens exactly as you left it.
The gap week
Europe and North America change their clocks on different weekends. For a week or two each spring and autumn, New York sits four hours from London instead of five — and every shared window moves with it.
It's an easy hour to lose in your head. Zoneline does the arithmetic with the same time-zone database your devices use, for any date you pick.
Who it's for
Standups, design reviews and launch calls across three continents, without the spreadsheet of offsets.
Offer times that land inside your client's working day, not just yours — and send them the link to prove it.
Plan interviews and first-week rituals with a new teammate in a new zone, before the first awkward 6am call.
No accounts, no calendar access, nothing to install. Add people, pick a window, send the link.
