World Clock — Current Time Around the World
Compare current time across world cities with interactive time strips. Drag on any city's time strip to explore future/past hours — all other cities move simultaneously. See also our Time Zone Converter, Time Zone Difference Calculator, and Countdown Timer.
How to Use the World Clock Time Zone Comparison
This world clock displays the current time in multiple cities with interactive color-coded time strips. The green marker shows the currently selected hour. To explore a different time, simply click and drag on any city's time strip — all other cities shift simultaneously, showing you exactly what time it will be everywhere at that moment.
Add cities by typing a name or country in the search box. Remove any city with the ✕ button. The offset number (e.g., +5, -3) shows the hour difference from your local time. Toggle between 12-hour and 24-hour format with the button. The color coding shows work hours (light), daytime, evening, and night periods at a glance.
This drag-to-compare feature is the fastest way to find meeting windows for distributed teams. Drag until all participant cities show their work-hours color (white/light blue area), and you've found an ideal meeting time. Click "Reset to Now" to return to live time. The strips show 48 hours of range centered on the current moment.
Meeting Scheduling Formula
Common Meeting Windows:
US East + Europe: 8–11 AM ET = 1–4 PM GMT = 2–5 PM CET
US West + Asia: 7–9 AM PT = 11 PM–1 AM JST (next day)
Europe + Asia: 8–10 AM CET = 3–5 PM SGT = 4–6 PM JST
US East + India: 8–10 AM ET = 5:30–7:30 PM IST
US East + Australia: 5–7 PM ET = 7–9 AM AEST (next day)
Time Zone Math:
Target Time = Your Time + (Their UTC offset - Your UTC offset)
Example: Scheduling a Global Team Call
Your team is in New York (UTC-4), London (UTC+1), and Tokyo (UTC+9).
London is +5h from New York. Tokyo is +13h from New York.
Drag the London strip until it shows 1 PM → automatically:
→ New York shows: 8 AM ✓ (work hours)
→ Tokyo shows: 9 PM ✗ (evening)
Try dragging to 12 PM London = 7 AM New York = 8 PM Tokyo (all reasonable)

Frequently Asked Questions
How do I drag to compare times?
Click and hold on any city's colored time strip, then drag left or right. As you drag, ALL cities shift together — showing you what time it will be everywhere at that selected hour. Release to stop. Click "Reset to Now" to return to the current live time. This is the fastest way to find meeting windows across time zones.
What do the colors in the time strips represent?
Green = currently selected/viewed hour. White-ish light blue = standard work hours (9 AM–5 PM). Sky blue = daytime outside work hours. Darker sky blue = early morning (6–8 AM) or evening (6–10 PM). Slate/gray = nighttime (10 PM–6 AM). This helps you instantly see who is awake and working.
Does this handle Daylight Saving Time?
Yes. The clock uses your browser's IANA timezone database which adjusts for DST automatically. The UTC offsets shown reflect the current DST status. Note that different countries switch at different dates — there are weeks where the offset between two cities may be unusual.
Why do some cities show a different date?
When the time difference crosses midnight, the date changes. If it's 11 PM Monday in New York, it's already Tuesday morning in Tokyo. Each city shows its actual local date. When you drag the time strip across midnight for a city, you'll see an orange date label appear indicating the day boundary.
What does the +/- number next to each city mean?
It shows the hour difference from YOUR local time. "+5" = that city is 5 hours ahead of you. "-3" = 3 hours behind. The ⌂ icon means same timezone offset as yours. Use it for quick mental math: if it's 2 PM for you and London shows +5, it's 7 PM in London.
How do I use this for remote team management?
Add all your team members' cities. The strips show at a glance who is in work hours, who is starting/ending their day, and who is asleep. Drag to find where work-hours colors overlap across all relevant cities — that's your meeting sweet spot. The visual approach beats offset arithmetic for teams spanning 3+ timezones.
Understanding World Time Zones
The world is divided into 24 primary time zones, each approximately 15 degrees of longitude wide. UTC (Coordinated Universal Time) is the global reference — all zones are expressed as offsets. In practice, zone boundaries follow political borders, making some zones irregular. China uses one timezone across 5 geographical zones; Russia uses 11.
Daylight Saving Time shifts clocks one hour forward in spring and back in fall for most of North America and Europe (on different dates). Countries near the equator typically skip DST. Some offsets are non-standard: India is UTC+5:30, Nepal UTC+5:45, and parts of Australia use UTC+9:30.
For global businesses, the "follow the sun" model works by handing off tasks between teams so work progresses 24/7 without overtime. The visual comparison in this tool makes designing such handoff schedules intuitive — drag to see exactly when work hours overlap and where gaps exist between your regional teams.
