Time Zone Converter & Meeting Planner — Plan Globally, Coordinated Instantly

Scheduling meetings across multiple continents and borders is complex and prone to scheduling errors. Our Online Time Zone Converter and Meeting Planner is a 100% serverless tool engineered to help you coordinate global team slots in a matter of seconds, without any friction.

🌎 Why Use a Multi-Timezone Scheduler?

When your team is scattered between San Francisco, London, Paris, Tokyo, and Sydney, setting a common calendar slot is a challenge:

• Auto-Detection: Automatically detects your local time zone upon opening the app.
• Unlimited City Database: Easily search and add any city or custom timezone to your timeline layout.
• Interactive Timelines: Visualize all 24 hours of the day on beautiful synchronized horizontal timelines. Use a single central slider to slide through the hours and see instant conversions across all cities.

📈 Meeting Comfort Score Algorithm

To prevent scheduling calls at 3 AM for teammates or during their valuable personal evening time, our platform computes a Comfort Score in real-time for every single hour of the day:

1. Working Hours (9 AM - 6 PM): Green Zone, optimal comfort (10/10 points).
2. Personal Hours (7 AM - 9 AM & 6 PM - 10 PM): Orange Zone, transition period (5/10 points).
3. Sleep Hours (10 PM - 7 AM): Red Zone, strictly to be avoided (0/10 points).

The planner averages the comfort scores across all active cities to highlight the absolute best windows to meet.

☀️ Robust DST (Daylight Saving Time) Simulator

Time zone offsets are dynamic throughout the year. Asynchronous Daylight Saving Time (DST) transition dates between Europe and North America, or the total absence of shifts in tropical regions, cause countless calendar errors.

Our application utilizes the browser's native JavaScript Internationalization API to query up-to-date IANA timezone database rules. Simply pick any future date, and the application will perfectly calculate the exact offsets in effect for that day.

📅 Effortless Collaboration & Calendar Exports

Once the best slot has been selected, coordinating with your guests is simple:

• Unique Shareable Link (URL Hash): Generate a unique scheduling URL containing your chosen parameters. Guests opening this serverless page will see the proposed times translated into their local timezone, and vote for their availability.
• Universal Calendar Integration: Export the meeting as an .ics (iCalendar) file, or click direct quick-add buttons to insert the event into Google Calendar, Outlook Web, or Apple Calendar.
