Why people convert Nairobi to Sri Lanka time

Scheduling a call from Nairobi to Sri Lanka: a 10:00 AM start in Nairobi lands at 12:30 PM in Sri Lanka, so you can confirm the slot without doing the arithmetic yourself.
Finding shared working hours: both Nairobi and Sri Lanka are inside the 9-to-5 working day between 9:00 AM and 2:30 PM EAT time (11:30 AM–5:00 PM IST). That is roughly 5 hours 30 minutes of usable overlap.
Booking travel or deliveries: tracking Sri Lanka local time against Nairobi keeps pickup windows and arrival estimates honest across the +2h 30m offset.

Always state the zone abbreviation, not just the hour. "3:00 PM EAT" is unambiguous; "3 PM" across a +2h 30m gap is not.
Block 9:00 AM–2:30 PM EAT as the recurring meeting window if you work primarily from Nairobi and need Sri Lanka colleagues present.
