24-Hour Reference Table

IST hours starting from midnight UTC. Times reflect today's DST status for Pacific Time.

IST (UTC+5:30)	Pacific Time

How It Works

Formula (Winter - PST, Nov - Mar)

PST = IST − 13:30

Example: 9:30 PM IST = 8:00 AM PST

Formula (Summer - PDT, Mar - Nov)

PDT = IST − 12:30

Example: 9:30 PM IST = 9:00 AM PDT

DST Note

India has no DST. The IST - PST gap shifts by 1 hour when US Pacific Time switches between PST and PDT in March and November. Pacific Time observes PST (UTC−8) from early November to mid-March, and PDT (UTC−7) the rest of the year.

Frequently Asked Questions

IST is 13 hours 30 minutes ahead of PST (winter) and 12 hours 30 minutes ahead of PDT (summer). The 30-minute component is fixed because IST is itself a half-hour offset (UTC+5:30), and PST is a whole-hour offset (UTC−8).

9:00 AM PST = 10:30 PM IST (same day, in winter). In PDT: 9:00 AM PDT = 9:30 PM IST. This means a 9:00 AM Pacific call typically requires India team members to join late in their evening.

The most common window is IST 9:30 PM - 11:30 PM = PST 8:00 AM - 10:00 AM. In summer (PDT), it shifts to IST 8:30 PM - 10:30 PM = PDT 8:00 AM - 10:00 AM. Early Pacific morning hours offer the most practical overlap without requiring either side to work outside reasonable hours.

Because IST itself is a half-hour offset (UTC+5:30), and PST is a whole-hour offset (UTC−8). The difference of 5.5 + 8 = 13.5 hours is unavoidable. This is a direct result of India's choice to use UTC+5:30 to align with its geographic center, while the US West Coast uses a standard whole-hour offset.
