Best Practices for PST-IST Meetings
- Rotate meeting times to share the burden of inconvenient hours
- Use 24-hour format to avoid AM/PM confusion
- Send calendar invites with both PST and IST times
- Account for daylight saving time changes (PDT vs PST)
- Provide meeting reminders in both time zones
- Consider time zone fatigue for regular meetings
Daylight Saving Time Considerations
Daylight Saving Time (DST) affects PST to IST conversion during certain periods:
Pacific Daylight Time (PDT)
During DST (March to November), PST becomes PDT (UTC-7):
- PDT to IST difference: 12.5 hours (instead of 13.5)
- Example: 9:00 AM PDT = 9:30 PM IST
Pacific Standard Time (PST)
During standard time (November to March):
- PST to IST difference: 13.5 hours
- Example: 9:00 AM PST = 10:30 PM IST
Important: Always verify whether DST is in effect when scheduling meetings. Our time zone converter automatically handles DST changes.
