NPT to EST Time Converter
EST is 9 hours and 45 minutes behind NPT. NPT is UTC+5:45, and The US East Coast is currently on EDT (UTC-4:00).
Best Time to Call Between NPT and EST
Standard 9-to-5 hours in these two zones never overlap, so someone has to take the call outside their working day. The most workable window is 5:00 PM to 10:00 PM NPT, which is 7:15 AM to 12:15 PM EST.

What NPT and EST Actually Are
NPT — Nepal Time
Kathmandu, Pokhara. Standing at UTC+5:45 as written, and the region does not change its clocks, so that offset holds all year. Nepal sits at UTC+5:45 — one of only two zones in the world on a 45-minute offset.
Nepal is deliberately 15 minutes ahead of India, an offset chosen so the country keeps its own time rather than sharing its neighbor's.
EST — Eastern Standard Time
New York, Toronto, Washington DC, Atlanta, Miami, Boston. Standing at UTC-5:00 as written, and the region does change its clocks, so its live offset moves by an hour twice a year. The next change is on Sunday, November 1, 2026, to EST. Australia also uses EST for its own Eastern Standard Time (UTC+10), now more often written AEST.
Eastern Standard Time is only actually in force from early November to mid-March. For the other eight months the same region is on EDT, which is why so many EST conversions are quietly wrong.
What This Means in Practice
Expect times on the half hour
NPT sits on a 45-minute offset rather than a whole hour, so a round number on one side is never a round number on the other. A 9:00 meeting becomes 45 minutes past the hour, which is exactly the detail calendar invitations get wrong when someone converts in their head.
The date changes mid-working-day
For 1 of the eight hours in a normal NPT working day, the equivalent EST time falls on a different calendar date. Anything scheduled in that stretch needs the date checked as well as the time, or a Tuesday call quietly becomes a Wednesday one at the other end.
This gap is not fixed
EST changes its clocks and NPT does not, so the difference between them moves by an hour twice a year. A recurring meeting set now will drift for one side from Sunday, November 1, 2026 unless someone resets it.

Frequently Asked Questions
What is the time difference between NPT and EST?
EST is 9 hours and 45 minutes behind NPT. That is the live figure. Taken strictly as written, the gap between NPT and EST is 10 hours and 45 minutes — the two differ because at least one of these regions is currently on daylight saving.
What is 9:00 AM NPT in EST?
9:00 AM NPT is 11:15 PM the previous day EST.
What are the best hours to schedule a call between NPT and EST?
Standard business hours in these two zones do not overlap at all, so one side has to work outside the 9-to-5. The most workable window is 5:00 PM to 10:00 PM NPT, which is 7:15 AM to 12:15 PM EST.
Does the difference between NPT and EST change during the year?
Yes. EST observes daylight saving and NPT does not, so the gap shifts by an hour at least twice a year. The next clock change is on Sunday, November 1, 2026.
Does NPT always mean Nepal Time?
Nepal sits at UTC+5:45 — one of only two zones in the world on a 45-minute offset.
Does EST always mean Eastern Standard Time?
Australia also uses EST for its own Eastern Standard Time (UTC+10), now more often written AEST.
