Why people convert PDT to SGT time
- Scheduling a call from PDT to SGT: a 10:00 AM start in PDT lands at 1:00 AM in SGT the next day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a +15h gap: PDT and SGT 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 SGT is 12:00 AM in PDT.
- Watching a live event or market open: PDT viewers need 12:00 AM in SGT to catch a 9:00 AM start there, and 9:00 AM if the event is anchored to PDT.
- Always state the zone abbreviation, not just the hour. "3:00 PM PDT" 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 PDT takes the early slot, the next week SGT does.
