Plan meetings across multiple time zones online free - no login. Enter your cities and find the best overlap time for international meetings, with a clear visual comparison across zones.
Scheduling across timezones is harder than it looks - daylight saving changes in different months, 'morning in New York' is 'late afternoon in London' but 'early next morning in Singapore'. This makes the overlap visible without mental math.
Enter your participants' cities and find the time windows where business hours overlap. Avoid scheduling meetings at 3am for one participant by seeing everyone's local time at a glance.
Schedule a video call between teams in different countries, find a meeting time that works for both a client and a remote team, plan a webinar that suits the majority of an international audience, coordinate a global product launch timing, schedule interviews across different timezones, and find overlap hours for async-first teams doing occasional live collaboration.
The most common question is why there is no good overlap time between certain cities. San Francisco and Singapore are 15–16 hours apart - a 9am SF meeting is midnight in Singapore. The only overlap of business hours occurs in the early morning for one side and late evening for the other. Teams handling this regularly often use asynchronous communication as the primary channel.

Common questions about this tool and how to use it.
US Eastern Time (ET) and India Standard Time (IST) are 9.5 hours (EST) or 10.5 hours (EDT) apart. The best overlap window: early morning ET / early evening IST. 8am ET = 6:30pm IST (EST winter) or 7:30pm IST (EDT summer). A 9am ET meeting is 7:30–8:30pm in India - within working hours for both sides if the Indian team accepts late-day meetings. Avoid afternoon ET - it becomes late night in India.
Daylight saving changes occur on different dates in different countries - the US changes in March and November, the EU changes in March and October, Australia changes in April and October. This means the offset between two time zones can shift twice a year, sometimes at different times. The safest approach: always specify meeting times in UTC (e.g., '14:00 UTC') so participants convert to their own local time, eliminating DST confusion entirely.
New York business hours: 9am–5pm ET. London business hours: 9am–5pm GMT/BST. Offset: 5 hours (EST) or 4 hours (EDT/BST). Overlap: 9am–5pm London = 4am–12pm New York (EST). Practical overlap: 9am–1pm New York / 2pm–6pm London (winter). Morning New York + afternoon London is the consistent overlap window, regardless of daylight saving - this 4-5 hour window accommodates most transatlantic meeting scheduling.
For ad-hoc meetings: a timezone converter or world clock app. For team scheduling: calendar tools with timezone display (Google Calendar, Outlook). For finding availability across multiple participants in different zones: scheduling tools like Calendly, Doodle, or When2meet show availability in each person's local time automatically. For async-first teams: establishing a 'team reference timezone' (often UTC) for all shared deadlines reduces daily timezone mental math.
This is the global scheduling challenge: Asia-Pacific (UTC+8 to +10), Europe (UTC+0 to +2), and Americas (UTC-8 to -5) span 13–18 hours. There is no standard business hours overlap for all three simultaneously. Options: rotate meeting time zones (each region takes an early/late call in turns), record meetings for async review, split into regional calls, or accept that one region always takes a non-ideal slot. The most equitable solution is rotating so no single region always bears the inconvenient time.
