Daylight Saving Time 2026 – US Dates
| Event | 2026 Date | What Happens |
|---|---|---|
| Spring Forward (DST begins) | March 8, 2026 | Clocks advance 1 hour at 2:00 AM |
| Fall Back (DST ends) | November 1, 2026 | Clocks go back 1 hour at 2:00 AM |
Note: Arizona (except Navajo Nation) and Hawaii do not observe Daylight Saving Time. Most of Europe observes DST on different dates (last Sunday in March / last Sunday in October).
Best Times to Schedule International Meetings
| Meeting Between | Best Window | Why |
|---|---|---|
| New York + London | 9 AM–12 PM EST | 2 PM–5 PM in London — normal business hours both sides |
| New York + India | 8 AM–10 AM EST | 6:30 PM–8:30 PM IST — end of India business day |
| New York + Singapore | 8 AM–9 AM EST | 9 PM–10 PM SGT — tight but workable |
| Los Angeles + Tokyo | 7 AM–9 AM PST | 12 AM–2 AM JST — difficult, asynchronous often better |
| London + Dubai | 9 AM–1 PM GMT | 1 PM–5 PM GST — overlaps well |

Frequently Asked Questions
UTC (Coordinated Universal Time) is the global time standard from which all other time zones are measured. It replaced GMT (Greenwich Mean Time) as the international standard, though both refer to the same base time. All time zones are expressed as UTC+ or UTC– an offset in hours (and sometimes 30 or 45 minutes). For example, Eastern Standard Time is UTC-5, meaning it is 5 hours behind UTC.
Most of Africa, Asia, and countries near the equator do not observe DST because seasonal daylight variation is minimal. In the US, Arizona and Hawaii skip DST. Japan, China, India, Singapore, and most of Southeast Asia do not use DST. Russia abolished DST in 2014 and stays on standard time year-round. The European Union voted to abolish DST but implementation has been delayed due to member state disagreements.
India Standard Time (IST) is UTC+5:30 — a half-hour offset rather than a full hour. This unusual offset exists because when India standardized its time zone in 1947, the half-hour split was chosen as a geographic compromise to cover the entire country with a single time zone. Several countries use 30-minute or 45-minute offsets, including Nepal (UTC+5:45), Iran (UTC+3:30), and parts of Australia.
The International Date Line (IDL) is an imaginary line at approximately 180° longitude in the Pacific Ocean where the calendar date changes. Crossing westward (e.g., from the US to Asia) moves you forward one calendar day. Crossing eastward (from Asia to the US) moves you back one day. This is why flights from the US to Japan often arrive “the next day” even after a 10-hour flight, while returning flights can land on the “same day” they departed.
Find the UTC offset for both locations, subtract to find the difference, then add or subtract that many hours from your local time. Example: converting 3 PM New York (UTC-5) to London (UTC+0) — the difference is +5 hours, so London time is 8 PM. For daylight saving, check whether either location is currently observing it, as this can change the offset by 1 hour. Our converter handles all of this automatically.
