Why people convert Kathmandu to Mexico City time
- Scheduling a call from Kathmandu to Mexico City: a 10:00 AM start in Kathmandu lands at 10:15 PM in Mexico City the previous day, so you can confirm the slot without doing the arithmetic yourself.
- Handling a -11h 45m gap: Kathmandu and Mexico City have no overlap inside a normal 9-to-5 day, so real-time meetings need an early-morning or late-evening slot on one side. 9:00 AM in Mexico City is 9:15 PM in Kathmandu.
- Watching a live event or market open: Kathmandu viewers need 9:15 PM in Mexico City to catch a 9:00 AM start there, and 11:45 AM if the event is anchored to Kathmandu.
- Always state the zone abbreviation, not just the hour. "3:00 PM NPT" is unambiguous; "3 PM" across a -11h 45m gap is not.
- With a -11h 45m gap there is no shared 9-to-5 window, so alternate the early start: one week Kathmandu takes the early slot, the next week Mexico City does.
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).
About CST (Central Standard Time)
Central Standard Time (CST) covers the central region of North America. It is the second most populous time zone in the US, including major cities like Chicago, Houston, and Dallas. CST is also used in Mexico City and much of Central America including Guatemala, Honduras, El Salvador, and Costa Rica. During summer, most of the US and Canada switch to Central Daylight Time (CDT, UTC-05:00), while Mexico and Central American countries generally remain on CST.
