Question 1

How do I find the best time for international meetings?

Accepted Answer

Add all relevant time zones to the world clock planner by searching for cities or countries. The tool displays current times side-by-side and highlights business hours for each location. Look for overlapping business hours (typically 9 AM - 5 PM local time) to find mutually convenient meeting times. The visual timeline helps identify windows where all participants are available.

Question 2

What is UTC and why is it important?

Accepted Answer

UTC (Coordinated Universal Time) is the primary time standard used worldwide. It doesn't change with daylight saving time and serves as a reference point for all time zones. When scheduling global meetings, using UTC as a reference prevents confusion: "Meeting at 14:00 UTC" is unambiguous regardless of where participants are located. Software developers often use UTC for timestamps and logs.

Question 3

How does the tool handle daylight saving time?

Accepted Answer

The world clock automatically accounts for daylight saving time (DST) transitions based on the current date. When you select a city, the tool uses the official time zone rules for that location, including DST observance. This ensures accurate time conversions during spring/fall transitions. Note that not all countries observe DST, and transition dates vary globally.

Question 4

Can I add custom time zones?

Accepted Answer

Yes! Search for any city, country, or time zone abbreviation. The tool includes hundreds of cities worldwide and recognizes common time zone names (EST, PST, GMT, etc.). You can add multiple time zones to compare simultaneously. Your selections are saved in browser storage, so your frequently-used time zones persist between sessions.

Question 5

How do I convert a specific time across time zones?

Accepted Answer

Click on any displayed time to set a reference time, and all other time zones update automatically. You can also use the time picker to select a specific date and time. The tool shows what time it will be in each location when it's that specific time in your reference zone. This is perfect for scheduling meetings or coordinating events.

Question 6

What are the colored indicators for business hours?

Accepted Answer

The timeline uses color coding to show time of day: Green indicates typical business hours (9 AM - 5 PM), Yellow shows early morning/evening (6 AM - 9 AM, 5 PM - 9 PM), Red indicates overnight hours (9 PM - 6 AM). This visual system helps you quickly identify times that work for all participants without scheduling meetings during someone's sleeping hours.

Question 7

Can I share my time zone comparison with others?

Accepted Answer

The tool generates shareable URLs that include your selected time zones and reference time. Copy the URL from your browser and send it to meeting participants. When they open the link, they see the same time zone comparison. This makes it easy to propose meeting times and get feedback from distributed teams.

Question 8

How do I account for different work schedules globally?

Accepted Answer

Standard business hours vary by country: US/Europe typically work 9 AM - 5 PM, Japan often works 9 AM - 6 PM, Middle East may work Sunday-Thursday, and some regions have split schedules (with afternoon breaks). When scheduling global meetings, consider: cultural norms around work hours, common lunch times (noon - 1 PM in most regions), religious observances (Friday afternoon for Muslim-majority countries), and national holidays.

Question 9

What if I need to schedule recurring meetings?

Accepted Answer

For recurring meetings, verify the time works during both standard time and daylight saving time periods. DST transitions can shift meeting times by an hour for some participants but not others. Use the date picker to check the meeting time during different months. Consider using UTC for recurring meetings to avoid ambiguity, then let participants convert to their local time.

Question 10

How accurate is the world clock time?

Accepted Answer

The tool syncs with your device's system clock and applies official time zone offset rules maintained by the IANA Time Zone Database. Accuracy depends on your device clock being correct. For mission-critical time coordination (financial trading, spacecraft operations), use official time services. For business meetings and scheduling, the tool provides sufficient accuracy (+/- 1 second).
