SGT vs IST: what's the time gap?
IST is 7 hours behind SGT. In everyday terms, once you know the time on one side you just subtract 7 hours to get the other — so a call between Singapore and Dublin is always 7 hours apart.
What time is it in IST right now?
Right now the time in Irish Standard Time (IST) is Monday, June 29, 2026 · 6:54:03 PM. It ticks every second, so you’re always looking at the live IST clock.
What time is it in SGT right now?
And in Singapore Time (SGT), it’s currently Tuesday, June 30, 2026 · 1:54:03 AM. Compare the two and the 7 hours gap is easy to see.
What's the best time for a SGT–IST call?
For example, a 9:00 AM SGT meeting takes place at 2:00 AM IST. The trick is to aim for a slot that lands inside normal working hours on both sides. Once you’ve found a time, hit Share on the converter to copy a link with the time built in — easy to send to a colleague. Juggling three or more zones? The meeting planner highlights the hours that overlap for everyone.
How does daylight saving affect SGT to IST?
The labels SGT and IST are fixed offsets, so the result on this page is always exact. One side switches between standard and summer time while the other stays put, so the real-world gap can shift by an hour for part of the year. It's worth checking which label a region is actually using before you lock in a time.
Why can you trust this SGT to IST converter?
Every conversion here is calculated from the IANA time zone database — the same source your phone, computer, and browser rely on. Plenty of tools hard-code a single offset, which quietly goes wrong whenever a region changes its rules or flips for daylight saving. We follow the real rules instead, so SGT to IST stays accurate for today and for any past or future date you type in.

Frequently asked questions
How many hours behind SGT is IST?
IST is 7 hours behind SGT — a fixed 7 hours difference, since both are fixed-offset labels.
What time is it in IST when it's 12:00 PM SGT?
When it's 12:00 PM (noon) SGT, it's 5:00 AM IST.
Do SGT or IST use daylight saving time?
Singapore Time (SGT) is a fixed offset with no daylight saving; Irish Standard Time (IST) observes daylight saving, alternating with GMT.
Why might the real-world SGT–IST difference change during the year?
The labels SGT and IST are fixed offsets, so this converter is always exact. But Irish Standard Time's region switches between standard and summer time, so for part of the year you may actually want SGT to GMT. Always check which label a region is currently using before you schedule.
