JST (Japan Standard Time) is 1 hours ahead of SGT (Singapore Time). This means when it's 12:00 PM in Singapore (SGT), it's 1:00 PM in Tokyo (JST).
The best time to call from SGT to JST is during overlapping business hours. For SGT callers, schedule between 9:00 AM - 12:00 PM SGT to ensure both parties are within standard business hours.
The time difference may change during daylight saving transitions if one region observes DST while the other doesn't. Singapore Time (UTC+8) and Japan Standard Time (UTC+9) may have different DST schedules.
SGT includes cities like Singapore. JST includes cities like Tokyo. Both time zones cover important business and cultural centers.
In 2025, DST in North America starts on March 9 at 2:00 AM and ends on November 2 at 2:00 AM. Other regions may have different DST schedules or not observe DST at all.
