PST to IST Converter
Understanding PST and IST Time Zones
Pacific Standard Time (PST)
Pacific Standard Time is observed in undefined and uses the offset UTC-8. Major cities in this time zone include Los Angeles, San Francisco, Seattle, Portland. This time zone serves a significant global region with important economic and cultural hubs.
India Standard Time (IST)
India Standard Time operates at UTC+5.5, covering undefined. Key cities include Mumbai, Delhi, Bangalore. The 13.5-hour forward offset from PST means that when professionals in Los Angeles start their workday at 9:00 AM, it is already 10:30 PM in Mumbai.
PST is also commonly referred to as Pacific Time, PT, West Coast time, LA time, California time. IST is also known as India time, Indian time, Mumbai time, Delhi time. So if you are searching for Pacific Time to India time, this is the same conversion as PST to IST.

Scheduling Between PST and IST
When coordinating deliverables across PST and IST, set deadlines in the earlier time zone to avoid end-of-day confusion. A "5 PM deadline" should specify which zone to prevent missed deliveries due to the 13.5-hour offset.
The large 13.5-hour gap between PST and IST means that finding overlapping working hours requires compromise from at least one side. Consider adopting asynchronous workflows — recorded video updates, shared documents, and time-zone-aware project management tools — to supplement the limited real-time overlap.
Travel Between Los Angeles and Mumbai
Flight times between Los Angeles and Mumbai often appear misleading because of the time zone shift. A departure at 10:00 AM PST arriving at 9.5:00 AM IST may look long, but remember to factor in the 13.5-hour offset.
Medical experts recommend allowing approximately one day of adjustment per hour of time difference. For the 13.5-hour shift between PST and IST, plan for roughly one week of gradual adjustment for optimal performance.
Daylight Saving Time Considerations
Countries near the equator — including Singapore, most of Africa, and parts of South America — do not observe DST, making their offsets constant year-round. This simplifies scheduling compared to US or European zones.
For the PST to IST conversion specifically: PST (UTC-8) observes DST, while IST (UTC+5.5) does not observe DST. This means the offset between them changes by one hour seasonally — the usual 13.5-hour gap becomes 12.5 or 14.5 hours during DST transitions.
