Time Zone FAQ

Yes! All calculations automatically adjust for future DST changes. If you look at a date in July, we show you the time offsets for July, not today. This means you can confidently schedule meetings weeks or months in advance without worrying about DST transitions throwing off your times.

The colors indicate how comfortable each time slot is for all participants. Green means everyone is within standard business hours (9 AM - 5 PM). Yellow means early morning or late evening hours for some participants (before 9 AM or after 6 PM). Red means someone would be meeting during sleeping hours (before 7 AM or after 10 PM). This helps you quickly find times that work best for everyone.

EST (Eastern Standard Time) is 5 hours behind GMT (Greenwich Mean Time). When it is 12:00 PM (noon) in London (GMT), it is 7:00 AM in New York (EST). During daylight saving time, EDT is 4 hours behind GMT.

PST (Pacific Standard Time) is 3 hours behind EST (Eastern Standard Time). When it is 9:00 AM in New York, it is 6:00 AM in Los Angeles. This difference remains constant year-round as both regions observe daylight saving time simultaneously.

The best time to call India from the US East Coast is between 7:00 AM - 9:00 AM EST, which is 5:30 PM - 7:30 PM IST in India. From the West Coast, call between 6:00 AM - 8:00 AM PST (7:30 PM - 9:30 PM IST). These times allow both parties to be awake during reasonable hours.

The optimal meeting time between London and New York is 2:00 PM - 5:00 PM GMT (9:00 AM - 12:00 PM EST). This window falls within standard business hours for both cities. Earlier times work better for London, while later times suit New York.

Tokyo is 14 hours ahead of New York during Eastern Standard Time (EST), and 13 hours ahead during Eastern Daylight Time (EDT). Japan does not observe daylight saving time, so the difference changes when the US switches clocks.

When it is 9:00 AM in New York (EST), it is 6:00 PM in Dubai (GST). Dubai is 9 hours ahead of New York. Dubai does not observe daylight saving time, so during EDT, Dubai is only 8 hours ahead.

In the United States, daylight saving time starts on the second Sunday of March (clocks spring forward 1 hour) and ends on the first Sunday of November (clocks fall back 1 hour). Europe follows different dates, and many countries like Japan, China, and India do not observe DST at all.

UTC (Coordinated Universal Time) and GMT (Greenwich Mean Time) are often used interchangeably, but they are technically different. UTC is the primary time standard used worldwide and is based on atomic clocks. GMT is a time zone. In practice, UTC and GMT show the same time, but UTC is the scientific standard.

To convert military (24-hour) time to regular (12-hour) time: Hours 00-11 are AM (00:00 = 12:00 AM, 01:00 = 1:00 AM). Hours 12-23 are PM (12:00 = 12:00 PM, 13:00 = 1:00 PM, etc.). Subtract 12 from hours 13-23 to get the PM hour.

California is in the Pacific Time Zone. During standard time (November-March), it observes PST (Pacific Standard Time), which is UTC-8. During daylight saving time (March-November), it observes PDT (Pacific Daylight Time), which is UTC-7.

Singapore is 13 hours ahead of US Eastern Time (EST) and 16 hours ahead of US Pacific Time (PST). During daylight saving time, the differences are 12 hours (EDT) and 15 hours (PDT). Singapore does not observe daylight saving time.

London (GMT/BST) and Singapore (SGT) have limited overlap. The best window is 8:00 AM - 9:00 AM London time, which is 4:00 PM - 5:00 PM Singapore time. This gives about 1 hour of overlap during standard business hours.

Australia is ahead of the US in time. Sydney is typically 16 hours ahead of New York (EST) and 19 hours ahead of Los Angeles (PST). The exact difference varies due to different daylight saving schedules - Australia's summer is during the US winter.

Forex markets operate 24 hours on weekdays across four major sessions: Sydney (5 PM - 2 AM EST), Tokyo (7 PM - 4 AM EST), London (3 AM - 12 PM EST), and New York (8 AM - 5 PM EST). The most volatile periods are when sessions overlap, especially London-New York (8 AM - 12 PM EST).

To find the best meeting time for a global team: 1) Identify the time zones of all participants, 2) Look for overlap during business hours (9 AM - 6 PM) for all locations, 3) If no overlap exists, rotate meeting times to share the inconvenience, 4) Use a visual meeting planner tool like WorldClock.lol to see overlap at a glance.

Golden hours are the time windows when all team members are within reasonable working hours (typically 8 AM - 8 PM local time). For teams spanning US and Europe, golden hours are usually 8-11 AM EST / 1-4 PM GMT. For US and Asia, try 7-9 AM PST / 11 PM - 1 AM Asia time. WorldClock.lol shows these overlaps visually with green highlighting.

For 24/7 coverage: 1) Map out all team members' time zones in WorldClock.lol, 2) Identify natural handoff windows where shifts overlap by 1-2 hours, 3) Schedule sync meetings during these overlap periods, 4) Use async communication tools for non-urgent items. The visual timeline helps you see coverage gaps and plan on-call rotations.

Visual time zone tools like WorldClock.lol let you see the full 24-hour picture at once, making it easy to spot overlap windows and avoid problematic times. Text-based converters only show one time at a time, requiring multiple lookups. The visual approach is especially valuable for teams across 3+ time zones where finding good meeting times requires seeing the big picture.

In WorldClock.lol, add all relevant cities and look for time slots where all locations show green (9 AM - 5 PM local) or yellow (7 AM - 9 AM or 5 PM - 8 PM local). The overlap is instantly visible as a vertical band of favorable colors. For teams spanning more than 10 hours, you may need to accept some yellow (early/late) slots.

A timezone overlap finder is a tool that identifies when business hours or awake hours align across multiple time zones. WorldClock.lol is a visual timezone overlap finder - it shows each city's 24-hour timeline with color-coded business hours, making it easy to spot where everyone's work day overlaps.

Look for green and yellow zones on WorldClock.lol's timeline - these indicate waking hours (roughly 7 AM - 10 PM). Red zones indicate likely sleeping hours. For a team spanning US, Europe, and Asia, the 'everyone awake' window is typically very narrow (1-2 hours) or may not exist, requiring some team members to join early or late.

While WorldClock.lol defaults to 9 AM - 5 PM as business hours, real teams have varying schedules. Use the visual timeline to identify overlap based on your team's actual hours. For example, if your Tokyo team works 10 AM - 7 PM JST, look for overlap with other cities during those hours, not the default 9-5.

For teams spanning US, Europe, and Asia, there's rarely a perfect time. Common approaches: 1) Early morning US / afternoon Europe / late evening Asia (e.g., 7 AM EST / 12 PM GMT / 8 PM SGT), 2) Late evening US / early morning Europe / afternoon Asia, 3) Rotate meeting times to share the burden. WorldClock.lol helps visualize these trade-offs.

WorldClock.lol is designed for remote engineering teams.

For gaming guilds: 1) Add all members' cities to WorldClock.lol, 2) Look for evening hours (6-10 PM local) overlap, 3) For US-EU guilds, evening US time catches late-night EU players, 4) Share the WorldClock.lol link in Discord so everyone can see the proposed raid time in their local zone.

Most game servers display times in their region's primary time zone: NA servers typically use Pacific Time (PT), EU servers use Central European Time (CET), and Asian servers use Japan Standard Time (JST) or China Standard Time (CST). Add the server's city to WorldClock.lol to convert event times to your local time.

In 2026, US Daylight Saving Time starts on March 8 (clocks spring forward) and ends on November 1 (clocks fall back). Europe changes on different dates: March 29 and October 25. Note that US and EU switch on different weeks, causing temporary 1-hour shifts in relative time for 2-3 weeks each transition.

DST can shift your regular meeting times by 1-2 hours during transitions. US and Europe change clocks on different dates, causing a 1-hour shift for 2-3 weeks twice a year. Countries like India, Japan, and China don't observe DST, so their offset with DST-observing countries changes. WorldClock.lol automatically adjusts for these changes.

New Year arrives first in the Pacific islands. Kiritimati (Christmas Island) in Kiribati celebrates first at UTC+14. Major cities celebrating early include Auckland, New Zealand (about 18 hours before New York) and Sydney, Australia. The last places are American Samoa and Baker Island at UTC-11/-12.
