Frequently asked questions
What is the time difference between Lisbon and IST?+
Lisbon is UTC+00:00 and IST is UTC+05:30 in standard time. The gap between them changes during the year if either place observes daylight saving, so enter a date to see the difference on that day.
Does Lisbon observe daylight saving time?+
Yes. In 2026 the clocks change on 29 March 2026 and 25 October 2026.
Does IST observe daylight saving time?+
No. IST stays on UTC+05:30 all year.
Why does one local time sometimes have two answers?+
When clocks go back, the hour before the change repeats, so that local reading happens twice and both instants are valid. When clocks go forward, the skipped hour never occurs, so that reading has no matching instant at all. The converter reports both cases rather than guessing.
