Why people convert Saudi Arabia to Kathmandu time
- Scheduling a call from Saudi Arabia to Kathmandu: a 10:00 AM start in Saudi Arabia lands at 12:45 PM in Kathmandu, so you can confirm the slot without doing the arithmetic yourself.
- Finding shared working hours: both Saudi Arabia and Kathmandu are inside the 9-to-5 working day between 9:00 AM and 2:15 PM AST time (11:45 AM–5:00 PM NPT). That is roughly 5 hours 15 minutes of usable overlap.
- Keeping family and friends in sync: knowing that 8:00 PM in Saudi Arabia is 10:45 PM in Kathmandu makes it easy to avoid calling at 3 AM.
- Always state the zone abbreviation, not just the hour. "3:00 PM AST" is unambiguous; "3 PM" across a +2h 45m gap is not.
- Block 9:00 AM–2:15 PM AST as the recurring meeting window if you work primarily from Saudi Arabia and need Kathmandu colleagues present.
About AST (Arabia Standard Time)
Arabia Standard Time (AST) is fixed at UTC+03:00 all year across Saudi Arabia, Qatar, Kuwait, Bahrain, Iraq and Yemen. None of these countries observes daylight saving time, so the offset never changes. The abbreviation collides with Atlantic Standard Time (UTC-04:00) used in eastern Canada and the Caribbean; this page covers the Arabian peninsula meaning. Arabia Standard Time is the same offset as Moscow Standard Time and East Africa Time, which makes scheduling with Europe straightforward — Riyadh is one hour ahead of Central European Time in winter and level with it during European summer time.
About NPT (Nepal Time)
Nepal Time (NPT) runs at UTC+05:45, one of only a handful of time zones worldwide that are not a whole or half hour from UTC. Nepal set its offset to 5 hours 45 minutes ahead of UTC in 1986 to mark the country's position between the 75°E and 90°E meridians; Kathmandu's solar time sits just over 5 hours 41 minutes ahead of Greenwich, so the 45-minute offset tracks the sun more closely than either 5:30 or 6:00 would. Nepal does not observe daylight saving time, so NPT is fixed all year. The offset makes Nepal 15 minutes ahead of India Standard Time (UTC+05:30) and 2 hours 15 minutes ahead of Dubai (UTC+04:00).
