These guides cover the time zone offset, working-hour overlap, and DST quirks for five major business corridors, including New York–London, US–India, and the brutal LA–Tokyo gap.
For visual, real-time scheduling across any combination of cities — not just pairs — use our interactive Time Zone Meeting Planner →. It handles DST transitions automatically, shows you a 24-hour timeline, and lets you add as many locations as you need.
Available City Pair Guides
New York → London
5-hour gap (4 during DST gap weeks). The world's busiest business corridor. Eastern Time to GMT/BST with a generous morning overlap window.
San Francisco → Bangalore
12.5-hour gap (13.5 in winter). The defining challenge for US–India tech teams. Two narrow windows, no DST on the India side.
Los Angeles → Tokyo
16-hour gap (17 in winter). Near-zero standard-hour overlap. Requires early morning or late evening compromise from one side.
London → Sydney
9–11 hour gap depending on season. Opposite-hemisphere DST creates a constantly shifting overlap that rewards seasonal planning.
Chicago → Berlin
7-hour gap (6 during DST mismatch weeks). The Midwest-to-Europe corridor with a comfortable morning-afternoon overlap and tricky March/October transitions.
How to Use These Guides
Each city-pair guide covers the full time zone relationship: the raw UTC offsets, how DST changes the math across the year, where the working-hour overlap actually lives, and practical tips from teams who schedule these meetings every day. Click through to any guide for a deep dive.
Need more than a pair? The interactive planner handles any number of cities simultaneously. Add New York, London, Bangalore, and Tokyo — see every overlap at once, with automatic DST warnings for upcoming transitions.
Why Time Zone Pair Planning Matters
Poorly scheduled meetings cost more than inconvenience. They lead to missed decisions and burned-out team members who consistently take the bad time slot. Teams that share the scheduling burden fairly, by rotating meeting times, respecting local working hours, and using async tools where possible, tend to do better than teams where one office always sacrifices.
These guides give you the raw data to make informed decisions. The planner gives you the tool to act on them. Together, they help you build meeting rhythms that work for everyone, not just the people in the headquarters time zone.
