Advanced Features

  • One → Many conversions Convert a single Mumbai time (live or custom) into multiple destination cards to compare local times at a glance.
  • Half-hour offset attention Mumbai uses IST (UTC+5:30). The 30-minute offset can cause ambiguous-looking calendar entries—our converter shows exact numeric offsets to avoid errors.

Practical Scheduling Tips

  • Best interview window (same day)

    A practical overlap is Mumbai 14:00–16:30 IST ↔ London 09:30–12:00 GMT (when London is on GMT). In BST (London +1) these map to Mumbai 14:00–16:30 ↔ London 10:30–13:00 — always confirm via the Info action during DST switch windows.

  • Morning meetings for India, late-morning for UK

    If Mumbai schedules morning interviews (09:00–11:00 IST), London participants will join in the early morning (04:30–06:30 GMT) — avoid these unless necessary for round-the-clock teams.

  • How to paste times clearly

    Copy both local date & time (use Copy) and paste like: “Mon 14:00 IST / Mon 09:30 GMT” to prevent misunderstandings—include timezone abbreviations when possible.

  • Why check DST for London

    India does not use DST; London does. Around the DST swap there are short periods when offsets shift — use the Info button to verify London’s current DST status before finalizing times.

FAQs

What is the exact offset between Mumbai and London?

Mumbai uses IST (UTC+5:30). London is on GMT (UTC+0) or BST (UTC+1) depending on the time of year. That makes Mumbai 5.5 hours ahead of London in GMT, and 4.5 hours ahead when London is on BST.

Does India observe DST?

No—India does not observe daylight saving time. Offsets for IST remain stable year-round; London’s offset can change for BST so verify with the Info action if needed.

Can I prepare multiple formatted times for invites?

Yes—use Custom mode to set a candidate Mumbai time, then copy formatted strings from each destination card to paste into invites, messages, or spreadsheets.

How It Works

  • Accepts one origin and many destinations using City, IANA or Abbreviation selectors.
  • Uses tzdb offsets for precise conversions so Live mode ticks in real time and Custom mode converts a static origin time across destinations.
  • Displays formatted local date/time and numeric offsets; flags when a converted time falls on a different calendar day.
  • Per-destination actions: Swap, Copy formatted time, Info (DST details), and Jet-Lag planner link.
