Why people convert Delhi to NPT time

  • Scheduling a call from Delhi to NPT: a 10:00 AM start in Delhi lands at 10:15 AM in NPT, so you can confirm the slot without doing the arithmetic yourself.
  • Finding shared working hours: both Delhi and NPT are inside the 9-to-5 working day between 9:00 AM and 4:45 PM IST time (9:15 AM–5:00 PM NPT). That is roughly 7 hours 45 minutes of usable overlap.
  • Keeping family and friends in sync: knowing that 8:00 PM in Delhi is 8:15 PM in NPT makes it easy to avoid calling at 3 AM.
  • Always state the zone abbreviation, not just the hour. "3:00 PM IST" is unambiguous; "3 PM" across a +0h 15m gap is not.
  • Block 9:00 AM–4:45 PM IST as the recurring meeting window if you work primarily from Delhi and need NPT colleagues present.

About IST (India Standard Time)

India Standard Time (IST) is the time observed throughout India and Sri Lanka. It is based on the 82.5°E meridian, passing through Mirzapur in Uttar Pradesh. India uses a single time zone despite spanning roughly 30° of longitude, which has been debated. IST does not observe daylight saving time. India is the world's most populous country, making IST one of the most-used time zones globally. The IT outsourcing industry and call centers operate primarily on IST, making the EST-to-IST conversion one of the most searched timezone conversions.

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).
