Why people convert Sri Lanka to WET time
- Scheduling a call from Sri Lanka to WET: a 10:00 AM start in Sri Lanka lands at 4:30 AM in WET, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Sri Lanka and WET are inside the 9-to-5 working day between 2:30 PM and 5:00 PM IST time (9:00 AM–11:30 AM WET). That is roughly 2 hours 30 minutes of usable overlap.
- Coordinating a Sri Lanka-based team with WET contacts: quoting times in the other side's local clock — not your own — removes the single biggest source of missed meetings.
- Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a -5h 30m gap is not.
- Block 2:30 PM–5:00 PM IST as the recurring meeting window if you work primarily from Sri Lanka and need WET colleagues present.
