Why people convert SGT to PDT time
- Scheduling a call from SGT to PDT: a 10:00 AM start in SGT lands at 7:00 PM in PDT the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -15h gap: SGT and PDT have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in PDT is 6:00 PM in SGT.
- Booking travel or deliveries: tracking PDT local time against SGT keeps pickup windows and arrival estimates honest across the -15h offset.
- Always state the zone abbreviation, not just the hour. "3:00 PM SGT" is unambiguous; "3 PM" across a -15h gap is not.
- With a -15h gap there is no shared 9-to-5 window, so alternate the early start: one week SGT takes the early slot, the next week PDT does.
