Kathmandu is 5 hours 45 minutes ahead UTC in winter and 5 hours 45 minutes ahead UTC in summer — 5.75 hours ahead of UTC in winter. Its standard offset is UTC+05:45, and it does not observe daylight saving, so the difference never changes. This page explains the difference, shows it month by month, and gives the conversion tables in both directions.

How far is Kathmandu from UTC?
The difference between Kathmandu and UTC is the offset: UTC+05:45 in standard time. When it is noon in Kathmandu, it is still morning in London — the day in Kathmandu is 5 hours 45 minutes ahead the day at Greenwich. The sign matters: a positive offset means ahead of UTC (east of Greenwich), a negative offset means behind it (west of Greenwich).
In practical terms, the difference means that the working day in Kathmandu (09:00–17:00 local) is 03:15–11:15 UTC in January and 03:15–11:15 UTC in July. A team that schedules in UTC needs to know both numbers, because a meeting set for 15:00 UTC is 20:45 in Kathmandu in January and 20:45 in July — and one of those may be outside the working day even when the other is inside it.
Kathmandu vs UTC through the year
The offset on the 15th of each month in 2026. If the table shows one value all year, Kathmandu does not observe daylight saving. If it shows two values, the change between them is the clock change.
| Month | Offset from UTC |
|---|---|
| January | UTC+05:45 |
| February | UTC+05:45 |
| March | UTC+05:45 |
| April | UTC+05:45 |
| May | UTC+05:45 |
| June | UTC+05:45 |
| July | UTC+05:45 |
| August | UTC+05:45 |
| September | UTC+05:45 |
| October | UTC+05:45 |
| November | UTC+05:45 |
| December | UTC+05:45 |
The clock changes are: in 2026, none; in 2027, none. For the full story, see the Kathmandu DST 2026 page and the daylight saving checker.
Conversion tables

Kathmandu to UTC, for the same eight hours:

| 18:00 | 12:15 | 12:15 |
| 21:00 | 15:15 | 15:15 |
Two things to watch in these tables. First, the date: a UTC time in the evening is the next day in Kathmandu when the offset is positive — 21:00 UTC is 02:45 the next day in Kathmandu in January — and a Kathmandu time early in the morning is the previous day in UTC when the offset is positive. Second, the season: the January and July columns are identical, because the offset never changes. The UTC to Kathmandu page has the full 24-hour table.
Daylight saving and the difference
Kathmandu does not observe daylight saving, so the difference from UTC is constant: UTC+05:45 on every day of the year. Nepal sits in the subtropics and has never observed daylight saving. It is famous instead for its unusual offset, UTC+5:45 — one of only two zones in the world on a 45-minute offset. That constancy is an advantage for scheduling — the difference never moves — but it also means the difference between Kathmandu and any place that does observe daylight saving moves twice a year, when the other place changes its clocks. The difference between Kathmandu and New York, for example, is 10 hours 45 minutes ahead in January and 9 hours 45 minutes ahead in July.
What the difference means for scheduling
For a team that works in UTC — software, aviation, science — the difference is the number you add to every UTC time to get Kathmandu time, and the number you subtract from every Kathmandu time to get UTC. The mistake is to use one number all year when there are two. The safe habit is to put the UTC time in every invitation as well as the local time, and to let the calendar do the conversion: a calendar event set in UTC moves correctly when daylight saving changes, and an event set in local time does not always.
For comparison, two other major cities: London is the same time UTC in January and 1 hour ahead UTC in July, and Tokyo is 9 hours ahead UTC all year. Kathmandu's difference of 5 hours 45 minutes ahead (January) sits between them in the sense that matters for scheduling: a meeting at 14:00 UTC is 19:45 in Kathmandu, 14:00 in London and 23:00 in Tokyo in January. The time in Kathmandu page has the working-hours tables, and the meeting planner finds the overlap for any pair of cities.

Adjusting to the difference — travel and jet lag
Travelling to Kathmandu from London means setting your watch forward by 5.75 hours in January — you lose time going east, and the first day feels short. Travelling the other way, from Kathmandu to London, you gain the hours back. The rule of thumb for jet lag is that it takes about a day to adjust for each hour of difference when travelling east, and a little less when travelling west — so a trip from London to Kathmandu in January takes most travellers about 6 days to fully adjust to, while the return trip is usually easier. The practical advice is the same in both directions: get sunlight in the morning at your destination, avoid naps longer than 20 minutes, and do not schedule important meetings for the first morning after you arrive.
The same arithmetic applies to remote work. If you are in Kathmandu and your team works in UTC, your working day of 09:00–17:00 local time is 03:15–11:15 UTC in January — so a stand-up at 09:00 UTC is 14:45 for you, and a stand-up at 16:00 UTC is 21:45. If those times are outside your working day, the meeting is in the wrong place in the day, and the fix is to move the UTC time, not to ask one person to work at midnight. The meeting time finder finds the hours that work for a whole team, and the time in Kathmandu page has the working-hours tables.
Frequently asked questions
How many hours is Kathmandu ahead of UTC?
Kathmandu is 5 hours 45 minutes ahead UTC in January and 5 hours 45 minutes ahead UTC in July. The difference is the same all year.
Is Kathmandu ahead of or behind UTC?
Kathmandu is ahead of UTC — its offset is positive (UTC+05:45 in January), so local time is later than UTC.

No. Kathmandu does not observe daylight saving, so the difference of 5 hours 45 minutes ahead never changes.
What is Kathmandu's UTC offset?
Kathmandu's standard offset is UTC+05:45, all year. Its IANA time zone is Asia/Kathmandu.
When it is midnight UTC, what time is it in Kathmandu?
It is 05:45 in January and 05:45 in July — the same day, because the offset is positive.
