Kathmandu & Colombo — Business & Scheduling Guide
Kathmandu (Nepal) is a developing economy between India and China, with key industries in tourism, hydropower, agriculture, and remittances. Colombo (Sri Lanka) is a South Asian island economy with strategic Indian Ocean positioning, known for tourism, tea, apparel, and IT/BPO services.

Nepalese business hours are typically 10 AM–5 PM Sunday–Friday, with Saturday as the weekend. Sri Lankan business hours are typically 8:30 AM–5 PM, with a growing technology outsourcing sector. Most teams find that late morning to early afternoon offers the widest window for collaboration.
