Singapore uses Singapore Time (SGT, UTC+8) year-round with no Daylight Saving Time. Singapore is situated near the equator, which means daylight hours barely vary throughout the year, making DST unnecessary. SGT aligns with Kuala Lumpur (MYT), Hong Kong (HKT), and China (CST).
New York City operates on Eastern Time — Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) in summer. US clocks spring forward on the second Sunday of March and fall back on the first Sunday of November. NYSE and NASDAQ market hours (9:30 AM–4:00 PM ET) make Eastern Time one of the most referenced zones in global finance.
Both Singapore and Atlanta may observe Daylight Saving Time, which means the offset between them can change twice a year. Here is what to expect each season.
| Period | Note | Singapore | Atlanta | Offset |

| Mar – late Mar | US clocks forward, some zones still on standard | GMT+8 (UTC+8) | EDT (UTC−4) | 12 hours |
| Late Mar – Oct current | Both on summer / daylight time | GMT+8 (UTC+8) | EDT (UTC−4) | 12 hours |
| Late Oct – early Nov | Clocks transitioning — check exact date | GMT+8 (UTC+8) | EST (UTC−5) | 13 hours |
The transition window typically lasts 1–2 weeks in spring and autumn. If you have a recurring weekly meeting near a clock change, verify the exact date to avoid a missed call.
