Common mistakes with London and Delhi
- Forgetting that the gap changes even though Delhi never touches its clocks: London does, so a meeting fixed in Delhi time moves by an hour for people in London.
- Rounding to the hour. Delhi is on UTC+5:30, so an invite set for “3 pm” elsewhere starts at half past or quarter to the hour there.
- Writing “GMT” all year for London. In summer the zone is British Summer Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
