Why people convert SGT to ICT time
- Scheduling a call from SGT to ICT: a 10:00 AM start in SGT lands at 9:00 AM in ICT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both SGT and ICT are inside the 9-to-5 working day between 10:00 AM and 5:00 PM SGT time (9:00 AM–4:00 PM ICT). That is roughly 7 hours of usable overlap.
- Coordinating a SGT-based team with ICT contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM SGT" is unambiguous; "3 PM" across a -1h gap is not.
- Block 10:00 AM–5:00 PM SGT as the recurring meeting window if you work primarily from SGT and need ICT colleagues present.
