Built for teams that
span the map.
Overlap exists because timezone scheduling is genuinely hard — and every existing tool made it feel even harder.
Why we built this
Scheduling a meeting between New York and London sounds simple — it's just five hours. But then you add someone in Karachi. And someone in Berlin. And suddenly you're mentally juggling four different clocks, trying to remember which ones observe daylight saving time, and second-guessing whether 3pm "their time" means before or after they've had lunch.
The tools that existed were either cluttered with ads, confusing to use, or just showed you a wall of clocks without telling you what to actually do with them.
Overlap does one thing: it shows you the green zone — the hours where everyone is awake and at their desk. Click a slot. Copy the link. Send it. Done.
How Overlap works
No magic. Just honest timezone math, done cleanly.
Select your timezones
Pick the cities your team is in — Pakistan, India, USA, UK, Germany, or any combination. Overlap groups cities by country and uses IANA timezone data so daylight saving time is handled automatically.
See the green zone
A 24-hour timeline appears, one row per timezone. Green cells = working hours (9am–6pm local). The overlap zone — where all rows are green — is immediately visible. No mental math required.
Click a time, share the link
Click any cell to select a meeting time. The tool shows the exact local time for every participant. Copy the link — your colleague opens it and sees their local time highlighted automatically.
What we believe in
Speed over features
Overlap loads in under a second and works with zero sign-up. We'd rather do one thing instantly than ten things slowly.
Privacy by design
Your timezone selections never leave your browser. No accounts, no tracking, no personal data stored on our servers. Ever.
Free, and staying free
The core tool is and will always be free. We sustain it through unobtrusive Google AdSense ads — not paywalls or data selling.
Built for the real world
We specifically built for the timezone pairs people actually use: USA–UK, Pakistan–UK, India–USA, Germany–USA. Not every city in the world — the ones remote workers actually need.
