Scheduling meetings across distributed teams is notoriously prone to confusion and missed calls. A 4:00 PM Thursday meeting in San Francisco is 8:00 AM Friday in Singapore and 9:00 AM Friday in Tokyo—meaning remote teammates may be scheduled on a completely different day or in the middle of the night.
Furthermore, Daylight Saving Time (DST) changes do not occur synchronously: the United States changes clocks in early March and November, the European Union changes in late March and October, Australia changes in April and October, and equatorial hubs like Dubai, Karachi, and Singapore do not observe DST at all. This Meeting Planner removes the mental arithmetic by calculating synchronized local times directly in your browser.
Using the ECMAScript Internationalization API, it evaluates the exact date and time you enter against the IANA time zone database, ensuring seasonal daylight saving shifts are accurately applied. Each destination hub is presented with a color-coded status card: green indicates standard business hours (9:00 AM to 6:00 PM), yellow highlights early morning or evening shoulder hours (7:00–9:00 AM or 6:00–9:00 PM), and red flags unsociable night hours (9:00 PM to 7:00 AM).
With clear weekday, month, and day readouts on every card, you can immediately identify date-boundary crossings before sending an invitation.
Coordinate international meetings across major global time zones in real time. Choose your base date, time, and home time zone to instantly view corresponding local times across 11 key international business hubs, complete with color-coded business hour indicators.

Set your home time zone to New York (EST) or Los Angeles (PST), set the time to morning hours (9:00 AM–11:00 AM), and inspect London and Paris cards to identify afternoon working slots (2:00 PM–5:00 PM).
Set an afternoon slot (such as 4:00 PM PST) to check early-morning slots (8:00 AM or 9:00 AM) for Singapore and Tokyo on the following business day, verifying that teammates are not called during the night.
Set London (GMT) as your base zone at 10:00 AM to verify that Dubai (2:00 PM), Karachi (3:00 PM), and Mumbai (3:30 PM) are all within productive, regular working hours.
Click the time zone buttons under 'Show Timezones' to toggle off irrelevant cities, reducing visual clutter and highlighting only the locations where your active participants reside.

Problem
Solution
A late-afternoon meeting scheduled in the Americas is frequently the following calendar day in Asia and Australasia. Always inspect the weekday and date line on the destination card, not just the hour.
Problem
Solution
Because different countries transition into and out of Daylight Saving Time on different calendar weekends (and countries like Dubai, Pakistan, and Singapore never change clocks), offsets shift by 1 to 2 hours between seasons.
Problem
Solution
Scheduling a meeting that displays red (9:00 PM to 7:00 AM) places participants in late-night or early-morning sleep hours. Adjust your base time until cards display green or yellow.
Problem
Solution
Selecting 12:00 AM instead of 12:00 PM shifts all worldwide destinations by 12 hours. Always double-check whether your intended time is mid-day or midnight.
When coordinating across continents, the morning hours (8:30 AM to 11:30 AM) of your westernmost team member almost always provide the best overlap with eastern colleagues.
A Friday afternoon meeting in North America or Europe falls on Saturday morning in Tokyo, Singapore, and Sydney, inadvertently cutting into teammates' weekends.
Use the pill buttons to deactivate hubs not involved in your meeting. Keeping 3 to 4 key hubs visible makes it easy to slide through times and spot green overlaps instantly.
The tool provides 11 key international financial and technology hubs (New York, Los Angeles, Chicago, London, Paris, Dubai, Karachi, Mumbai, Singapore, Tokyo, Sydney) rather than an open directory of all 400+ IANA geographic zones.
Status colors use fixed thresholds (Green: 9 AM–6 PM, Yellow: 7–9 AM and 6–9 PM, Red: 9 PM–7 AM) and do not support customized working hour policies (such as 10 AM–7 PM or shift schedules).
The planner is an interactive visual schedule finder; it does not export .ics invite files or synchronize directly with Google Calendar or Microsoft Outlook.

Common questions regarding how the Meeting Planner handles daylight saving time, business hour thresholds, date boundary crossing, and multi-hub scheduling.
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.
