Time Zone Meeting Scheduler
Visually find the "Golden Hours" for globally distributed teams.
Struggling to find a time to meet with a globally distributed team? Add your participants below, and we'll map out a 24-hour day to find the Golden Hours where everyone is awake and in standard business hours (8 AM - 6 PM).
Participants
How to Use
Add all participants with their time zones
Select each team member's IANA timezone from the dropdown and add them to the scheduling grid.
Review the 24-hour timeline visualization
See color-coded blocks showing each participant's business hours, off-hours, and sleep windows across the full day.
Identify the Golden Hours overlap
Find the time columns where all participants show green business-hours blocks simultaneously.
Choose the best or least-bad meeting time
If no perfect overlap exists, select the window that minimizes off-hours burden across the team.
What are Golden Hours?
Golden hours are the time slots during the 24-hour day where all participants across different global timezones are awake during standard business hours (typically 8AM to 6PM local time).
Real-World Examples & Use Cases
Distributed Engineering Team Standups
Software teams spread across multiple continents need a daily standup time that works for everyone. A team with members in San Francisco (UTC-8), London (UTC+0), and Bangalore (UTC+5:30) has only a narrow window where all three are in business hours simultaneously. San Francisco 8 AM = London 4 PM = Bangalore 9:30 PM. The meeting scheduler visualizes this overlap immediately, showing that either San Francisco needs an early standup or Bangalore participates in the evening — helping the team make a fair, informed decision.
International Client Calls and Sales
Account managers and sales teams working with clients in different regions need to schedule calls without forcing clients to join at unreasonable hours. Knowing that a New York–Tokyo call inherently requires someone to be outside business hours, the scheduler identifies the least-bad options: Tokyo 8 AM = New York 7 PM, or New York 8 AM = Tokyo 10 PM. This helps account managers offer clients slots that are inconvenient for themselves rather than the client, improving satisfaction and professionalism.
Remote Work Policy and Scheduling Guidelines
HR teams and managers building remote work policies need to understand the timezone landscape of their teams. If a company has staff from Los Angeles to Warsaw, the scheduler reveals the realistic overlap window and whether a 'core hours' policy (e.g., all staff available 10 AM–2 PM in a reference timezone) is feasible. It also helps set expectations: teams spanning 12+ time zones like US West Coast and Southeast Asia face near-zero mutual business hours and require asynchronous-first communication policies.
Conference and Webinar Global Scheduling
Event organizers hosting live webinars, online conferences, and virtual workshops for global audiences need to choose time slots that maximize attendance. The meeting scheduler shows which time slots reach the most participants in their business hours. A single 60-minute webinar slot inevitably disadvantages some regions — the tool helps organizers decide whether to run two sessions (morning Americas/Europe and morning Asia-Pacific) or identify a single compromise slot that works reasonably well across target regions.
How It Works
Golden Hours Calculation Logic: Core algorithm: 1. Convert each participant's timezone offset to UTC at the current date (accounting for DST using IANA timezone database) 2. For each hour H from 0 to 23 (UTC): a. Convert H to each participant's local hour: localHour = (H + tzOffsetHours + 24) % 24 b. Check if localHour falls within business hours: isBusiness = 8 <= localHour <= 18 (configurable) isSleep = 23 >= localHour >= 7 (overnight sleep window) 3. Golden Hour = UTC hour where ALL participants have isBusiness=true 4. Acceptable Hour = UTC hour where isSleep=false for ALL participants Timezone offset considerations: - Offsets are not always whole hours: India (UTC+5:30), Nepal (UTC+5:45), parts of Australia (UTC+9:30), Iran (UTC+3:30) - DST shifts occur on different dates in different countries (US/Canada spring-forward and fall-back dates differ from EU dates) - IANA timezone database (via Intl.DateTimeFormat API in browsers) provides the correct offset for any timezone at any date Antipodal timezone example (near-zero overlap): New York (UTC-5) and Tokyo (UTC+9) are 14 hours apart NY 8AM (business) = Tokyo 10PM (sleep) ❌ Tokyo 9AM (business) = NY 7PM (evening, acceptable?) ✓ minimal overlap
