PST IST Time

This tool converts a given timestamp from Pacific Time (PST/PDT) to Indian Standard Time (IST). It supports standard and daylight saving time, applying the correct UTC offsets to produce an IST result.
Conceptually, the calculation uses the source offset (PST = UTC-08:00; PDT = UTC-07:00) to derive UTC, then adds IST (UTC+05:30). It handles date boundaries, leap years, and DST transitions without external data.
The primary users are developers building scheduling integrations, operations teams coordinating across continents, and travelers planning meetings or flights. The value lies in accuracy, consistency, and immediacy for cross‑zone planning. Unique differentiators include explicit DST handling embedded in the logic, avoidance of flaky manual offsets, and a simple, parsable output for automation. Core features cover input validation, DST awareness, deterministic results, and ISO-like formatting suitable for logs and calendars. Use cases include booking calls between the US West Coast and India, logging events in a shared system, and creating automated reminders that respect IST when planning across days and months.
