🌍 Cross-Timezone Meeting Planner

What can the Cross-Timezone Meeting Planner do?

The Cross-Timezone Meeting Planner helps distributed teams quickly find meeting times suitable for all participants. Add timezones for each participant, select a time, and the tool automatically shows corresponding times across all timezones with color-coded indicators for work hours, acceptable hours, and unsuitable hours.

Core Features

• Multi-Timezone Comparison: Add any number of timezones simultaneously, with real-time display of corresponding times
• Smart Color Coding: Green = work hours (9-18), Yellow = acceptable (8-22), Red = unsuitable (22-8)
• 24-Hour Timeline: Visual display of suitability across all hours for each timezone
• Quick Presets: One-click add for Beijing, New York, London, Tokyo, and other common cities
• Automatic DST Handling: Uses browser Intl API for automatic daylight saving time adjustments
• Time Slider: Drag to quickly browse different time points across timezones

How to Use

1. Click quick-add buttons or select timezones from the dropdown

2. Choose a date and reference time (default: 9:00 in first timezone)

3. Drag the time slider to browse different time points

4. Observe color indicators for each timezone and select a time when all participants are in green or yellow

Use Cases

Case 1: Daily Standup for International Teams

US-China teams need to schedule daily standups. Use this tool to quickly find overlapping work hours, avoiding late-night meetings for either side.

Case 2: International Client Meetings

When meeting with European, American, and Asian clients simultaneously, find a time window acceptable to all three parties.

Case 3: Remote Interview Scheduling

HR scheduling cross-border interviews can confirm local times for both interviewer and candidate, avoiding timezone confusion.

Extended Knowledge

The world is divided into 24 standard time zones, each offset by 1 hour. However, daylight saving time (DST) causes actual offsets to vary seasonally. For example, US Eastern Time is UTC-4 during DST and UTC-5 otherwise. This tool uses the IANA timezone database (via the browser's Intl API) to handle DST adjustments automatically.
