Why people convert PST to PDT time
- Scheduling a call from PST to PDT: a 10:00 AM start in PST lands at 11:00 AM in PDT, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both PST and PDT are inside the 9-to-5 working day between 9:00 AM and 4:00 PM PST time (10:00 AM–5:00 PM PDT). That is roughly 7 hours of usable overlap.
- Watching a live event or market open: PST viewers need 10:00 AM in PDT to catch a 9:00 AM start there, and 11:00 PM if the event is anchored to PST.
- Always state the zone abbreviation, not just the hour. "3:00 PM PST" is unambiguous; "3 PM" across a +1h gap is not.
- Block 9:00 AM–4:00 PM PST as the recurring meeting window if you work primarily from PST and need PDT colleagues present.
