PDT naar IST Converter.

PDT (Los Angeles, -07:00) to IST (Mumbai, +05:30) is currently a +12h 30m conversion. Live coverage on the PDT side is anchored by Los Angeles, Tijuana, San Diego, and Mexicali; the IST side draws from Mumbai, Delhi, Bengaluru, and Hyderabad.

PDT to IST matters whenever Los Angeles and Mumbai need to coordinate across a +12h 30m gap. The PDT side covers United States and Mexico, while IST covers India and Israel — that country mix is the practical reason this conversion shows up in calendars rather than the abstract offset math.

This pair is trans-Pacific, with one side in the Americas and the other in Asia or Oceania. The +12h 30m gap is large enough that morning on one side reliably overlaps evening on the other, which is why this conversion mostly serves global supply chains, gaming launch schedules, and follow-the-sun engineering.

PDT follows seasonal clock changes through America/Los_Angeles, while IST stays on a fixed offset year-round. That asymmetry is the real differentiator on this page: the gap widens or narrows by an hour twice a year, so calendar invites scheduled in one season often look wrong in the other.

PDT and IST sit 12h 30m apart, which leaves no shared 9-to-5 block. Live meetings have to bend one side's day, so most teams settle for one of two narrow windows: very early on the late side, or very late on the early side. That makes async messages, recorded standups, and clear handoff notes more valuable than calendar invites.
