Why people convert PDT to ART time
- Scheduling a call from PDT to ART: a 10:00 AM start in PDT lands at 2:00 PM in ART, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both PDT and ART are inside the 9-to-5 working day between 9:00 AM and 1:00 PM PDT time (1:00 PM–5:00 PM ART). That is roughly 4 hours of usable overlap.
- Watching a live event or market open: PDT viewers need 1:00 PM in ART to catch a 9:00 AM start there, and 8:00 PM 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 +4h gap is not.
- Block 9:00 AM–1:00 PM PDT as the recurring meeting window if you work primarily from PDT and need ART colleagues present.
