Quick Time Finder
Right now in Singapore: 5:16 AM
⚡ Quick Answer
Singapore is 13 hours ahead of New York (12 hours when NYC observes daylight saving time). The best time for business calls is 7:00 PM - 11:00 PM EST, which reaches Singapore during their morning hours (8:00 AM - 12:00 PM SGT next day).
Alternative: Early morning NYC (6:00-8:00 AM EST) catches Singapore's evening (7:00-9:00 PM SGT), but this is after standard business hours.
📞 Best Calling Windows
| Your Time (NYC) | Singapore Time | Recommendation |
|---|---|---|
| 6:00 AM - 8:00 AM | 7:00 PM - 9:00 PM | ⚠️ After hours (personal/urgent only) |
| 9:00 AM - 6:00 PM | 10:00 PM - 7:00 AM | ❌ Night/very early morning |
| 7:00 PM - 11:00 PM | 8:00 AM - 12:00 PM (next day) | ✅ BEST - Morning Singapore |
| 11:01 PM - 2:00 AM | 12:01 PM - 3:00 PM | ✅ Good (but very late for you!) |
🕐 Time Difference Alert
Singapore does NOT observe daylight saving time. Singapore Time (SGT, UTC+8) remains constant year-round.
When NYC switches to EDT in March, the difference becomes 12 hours instead of 13. When NYC returns to EST in November, the gap returns to 13 hours. The good news: this actually improves your calling window slightly during US summer!
Coordinating calls between New York and Singapore requires significant schedule flexibility due to the 13-hour time difference. There is essentially no overlap between standard 9-to-5 business hours in both cities — when NYC wakes up, Singapore is winding down, and when Singapore starts their workday, NYC is sleeping.
Singapore is the financial and tech hub of Southeast Asia, with a highly efficient, English-speaking business environment. Many professionals in Singapore are accustomed to late evening or early morning calls with US contacts, especially in tech, finance, and international business sectors. The key is finding a mutually acceptable time and sticking to it consistently.
This guide covers practical strategies for reaching Singapore contacts, understanding their work culture, and making the most of limited overlap opportunities between the two financial capitals.
🌍 Understanding the Time Gap
Evening NYC (7-11 PM EST)
Singapore time: 8 AM - 12 PM (morning, next day)
Pros: Catches Singapore professionals at the start of their day when they're fresh and responsive. This is the most practical window for regular business calls.
Cons: Late for you. Best for scheduled standing calls rather than ad-hoc conversations.
Very Late NYC (11 PM - 2 AM EST)
Singapore time: 12 PM - 3 PM (midday)
Pros: Mid-day Singapore, post-lunch when energy returns.
Cons: Extremely late for you. Only viable for critical issues or pre-arranged calls.
Early Morning NYC (6-8 AM EST)
Singapore time: 7-9 PM (evening)
Pros: Catches Singapore professionals before they sign off, though many have already left.
Cons: After standard business hours. Better for personal calls or urgent matters with contacts who work late.
💬 When Async Makes Sense
Given the challenging time difference, consider asynchronous communication for routine updates:
🎥 Video Messages
Tools like Loom or Slack video messages let you share updates without live calls.
✓ Best for: Project updates, presentations, demos
📧 Detailed Emails
Well-structured emails can replace many calls when thoughtfully written.
✓ Best for: Status reports, decisions, action items
📝 Shared Documents
Google Docs/Notion with comments enable async collaboration.
✓ Best for: Editing, planning, brainstorming
🔄 Rotating Schedule
Alternate who takes the inconvenient time slot (fairness matters!).
✓ Best for: Regular team syncs, weekly check-ins
📞 Calling NYC from Singapore
If you're in Singapore calling New York contacts:
| Your Time (Singapore) | NYC Time | Recommendation |
|---|---|---|
| 9:00 AM - 2:00 PM | 8:00 PM - 1:00 AM | ❌ Too late in NYC |
| 10:00 PM - 2:00 AM | 9:00 AM - 1:00 PM | ✅ BEST - Morning NYC |
| 7:00 PM - 9:00 PM | 6:00 AM - 8:00 AM | ⚠️ Early, but workable |
💡 Pro tip: Many Singapore tech companies have employees work late hours (10 PM - 2 AM SGT) specifically to overlap with US business hours. If you're in such a role, coordinate with your NYC contacts for 10-11 PM SGT calls (9-10 AM NYC).
