How to find the best meeting time for your remote team
1. Add your cities
Search any city worldwide from our database of over 140 cities. Add up to 10 cities. Your local city is detected automatically on first load using your browser's timezone setting — no location permissions required.
2. Find the green zone
The colour-coded 24-hour grid shows working hours, early morning, evening and sleep time for every city simultaneously. Green columns mean everyone is working at the same time — that's your ideal meeting window. The overlap detection runs automatically and highlights the best available slot.
3. Schedule the meeting
Click any column to select that time. View each team member's local clock in the meeting card. Copy a shareable link, export directly to Google Calendar, generate a ready-to-paste invite message, or embed the timezone widget in Notion, Confluence, or your team wiki.
Supported cities and timezone regions
Overlap Timezone includes over 140 cities across every major timezone region in its built-in database. Coverage spans North America (New York, Los Angeles, Chicago, Toronto, Vancouver, Mexico City), Europe (London, Paris, Berlin, Amsterdam, Stockholm, Warsaw, Istanbul, Moscow), Asia (Tokyo, Singapore, Mumbai, Dubai, Shanghai, Seoul, Hong Kong, Bangalore, Jakarta), Oceania (Sydney, Melbourne, Auckland), Africa (Lagos, Nairobi, Cairo, Johannesburg), and South America (São Paulo, Buenos Aires, Bogotá, Lima). If your city is not in the list, the search automatically falls back to OpenStreetMap's Nominatim geocoder to find any city worldwide.
Frequently asked questions
What is timezone overlap?
Timezone overlap is the window when all members of a distributed team are simultaneously within their normal working hours. A team with members in New York, London, and Singapore typically has only 1–2 hours of true overlap per day. Finding this window is critical for scheduling standups, sprint planning, and team retrospectives that include everyone.
How is this different from other timezone tools?
Most timezone converters handle one-to-one conversions — you enter a time in one city and see it in another. Overlap Timezone shows a full 24-hour colour-coded grid for all cities simultaneously, making the overlap window instantly visible at a glance. No login required, no signup, and it works as a self-contained offline-capable page. It also generates shareable meeting links, Google Calendar exports, and embeddable widgets for team documentation.
Does it handle Daylight Saving Time?
Yes. All timezone calculations use the browser's native Intl.DateTimeFormat API, which automatically handles DST transitions based on the current date. The grid always shows today's actual UTC offsets — you never need to manually adjust for summer or winter time. This is especially important for US–Europe teams, where DST switch dates differ by 2–3 weeks in March and October.
Is my data private?
Absolutely. Your city selections are stored only in the URL and in your browser's localStorage. No personal data is transmitted to or stored on any server. Overlap has no backend, no user accounts, and no tracking cookies. Read our full privacy policy for details.

Why Overlap Timezone is different
Unlike traditional timezone converters that require you to manually enter times and mentally compute overlaps, Overlap Timezone is purpose-built for the question remote teams actually ask: "When is everyone awake at the same time?" The visual grid makes the answer immediately obvious — green columns are where your team overlaps, and you can click to schedule directly from there.
When no perfect overlap exists — common for teams spanning Asia, Europe, and the Americas — Overlap scores every UTC hour and recommends the best-effort compromise slot. This "least-bad" recommendation factors in each team member's local hour and favours working hours over early mornings or late evenings. The result is a data-driven scheduling decision instead of guesswork.
Built for remote teams, freelancers and global companies
Overlap Timezone is used by engineering teams coordinating standups across continents, freelancers scheduling client calls in multiple timezones, international podcasters booking guests across time differences, digital agencies managing clients and delivery teams in different regions, and open source maintainers running community meetings for globally distributed contributors.
The tool is completely free, requires no login or account creation, stores nothing on a server, and works offline after the initial page load. It is hosted on Cloudflare Pages for fast global delivery and is actively maintained with timezone database updates, new city additions, and feature improvements.
