San Francisco to Singapore Time Converter

Connect two major tech innovation hubs with precise time conversions. Essential for global tech collaboration and follow-the-sun development workflows.

  1. Start with San Francisco

    Select San Francisco as your origin. It uses Pacific Time which switches between PST (UTC-8) and PDT (UTC-7) for Daylight Saving.

  2. Target Singapore

    Add Singapore as your destination. It maintains consistent Singapore Standard Time (SGT, UTC+8) throughout the year.

  3. Choose Your Time View

    Use Live mode for real-time comparison or enter a specific time to see how tech business hours align between these innovation hubs.

  4. Apply Your Conversion

    Leverage time segment colors to identify optimal meeting times, copy results for scheduling, or explore additional planning tools.

Key Advantages for Tech Collaboration

  • Handles Significant Time Difference Manages the 15-16 hour gap effectively, clearly indicating date changes and optimal collaboration windows for tech teams.
  • Optimized for Tech Industry Collaboration Specifically designed for Silicon Valley-Singapore tech partnerships, with insights on follow-the-sun development workflows.
  • Visual Time Segment Indicators Color-coded time segments help quickly identify whether converted times fall within work hours, evenings, or overnight periods.

Strategic Tech Scheduling Insights

  • Follow-the-Sun Development

    The time difference enables continuous productivity: SF teams can hand off work to Singapore teams at day's end, creating a 24-hour development cycle.

  • Optimal Meeting Windows

    The small overlap occurs in late afternoon SF time (4-5 PM PDT) which is morning in Singapore (7-8 AM SGT). Perfect for daily standups.

  • Historical Time Context

    Singapore adopted UTC+8 in 1982 to align with trading partners, while SF has observed DST since 1918. This historical difference affects modern business.

  • Tech Event Planning

    When planning virtual events between these tech hubs, consider that SF morning events (9 AM PDT) occur at midnight Singapore time—adjust accordingly.

Tech Collaboration Questions Answered

What is the time difference between San Francisco and Singapore?

Singapore is 15 hours ahead of San Francisco during Pacific Daylight Time (PDT) and 16 hours ahead during Pacific Standard Time (PST).

How does the time difference affect tech collaboration?

The 15-16 hour difference actually enables "follow-the-sun" development where work can continue nearly 24 hours between the two tech hubs.

Are there any good overlapping business hours?

A small 1-2 hour window exists: SF late afternoon (4-5 PM) corresponds to Singapore morning (7-8 AM), suitable for daily syncs.
