How to Use World Time Hub

A complete guide to getting the most out of all three free tools in World Time Hub.

🌍

World Time Now — Live Global Clocks

An interactive 3D globe showing live local times for every city on Earth, updated every second. Rotate, zoom, search and explore.

Navigating the globe

1
Rotate the globe
Click and drag to spin the globe freely. On mobile, use one finger to rotate.
2
Zoom in and out
Scroll your mouse wheel to zoom. On mobile, use a pinch gesture. Zooming in makes smaller countries easier to click.
3
Click a city dot
Click any yellow or blue dot on the globe to see that city's local time, timezone, and UTC offset.
4
Read day/night indicators
Yellow dots = daytime. Blue dots = nighttime. Instantly see which parts of the world are awake right now.

Searching for a city

5
Use the search bar
Type any city name — results appear instantly. Click a result and the globe rotates to that location with an animated pin.
6
Read the time panel
The panel shows the city's current local time, timezone name, UTC offset, and whether it's day or night.

💡 Tips

For travel: Search your destination to instantly see the local time and how far ahead or behind it is from home.

For quick scheduling: Glance at the globe before a call — a yellow dot means daytime, blue means they may be asleep.

🕐

Find Time Overlaps — Timezone Scheduler

Add multiple cities and see a 24-hour UTC timeline with each city's working hours highlighted. The golden overlap cells show when everyone is online at the same time.

Using the tool

1
Search and add cities
Type a city name in the search bar and select it from the dropdown. Click + Add. Repeat for each city your team is in.
2
Set working hours
Adjust the From and To hour inputs to match your team's actual working hours. The default is 9am–5pm local time per city.
3
Read the timeline
Amber cells = that city's working hours. Bright gold cells = overlap hours where all cities are working simultaneously. The blue-outlined cell is the current UTC hour.
4
Read the summary
Below the timeline, the shared working windows are listed in UTC and converted to each city's local time — ready to paste into a calendar invite.

💡 Tips

No overlap found? Try widening the working hours range slightly — even 30 minutes of overlap can work for a short standup.

Async teams: Even if there's no overlap, the timeline shows when each city is active, helping you plan handoffs and async deadlines.

📅

Holiday Overlap — Shared Public Holidays

Add countries, select a year, and instantly see every date where two or more of your selected countries share a public holiday — grouped by month.

Using the tool

1
Search and add countries
Type a country name in the search bar and select it. Click + Add. Add at least two countries to compare.
2
Select a year
Use the year dropdown to choose any year from 2025 to 2028.
3
Click Find Overlap
Results appear grouped by month. Each shared date shows the holiday name and which countries observe it on that day.
4
Use the results
Avoid scheduling key meetings, launches, or deadlines on shared holiday dates. Or use them to plan coordinated team days off.

💡 Tips

Project planning: Run the tool at the start of each quarter or year to flag shared holiday blackout periods for your international stakeholders.

Multi-country contracts: Add all countries involved in a contract to make sure SLA dates don't fall on public holidays in any signatory country.
