【Important】US Summer Time Begins Today!
Beware of the “1-hour difference” with London
March 9, 2026: Entering an irregular period in the market schedule
To all traders, thank you for your hard work. Today,March 9, 2026 (Monday)the U.S. market has moved to daylight saving time.
Note: London and the European markets are still on standard time!
This state of “summer time only in the U.S.” will continue untilMarch 29for about three weeks. Let’s be aware of the specific pitfalls during this period.
1. NY close and major indicators move an hour earlier
All times in Japan are moved one hour earlier. Pay close attention to carrying positions overnight, especially in the early morning.
| Item | Standard time (until last week) | Daylight saving time (today onward) |
|---|---|---|
| NY Close | 7:00 AM | 6:00 AM |
| Major U.S. Indicators | 10:30 PM | 9:30 PM |
2. Liquidity changes (the dreaded overlap time)
The overlap between London (standard time) and NY (daylight saving) shifts by one hour compared to usual. As a result,shortly after the NY open at 10:30 PM, European activity is still vigorousand will collide with it, making fluctuations more volatile than usual.
■ Until March 29, remind yourself: “It’s always one hour different!”
A clearly defined standard that is not swayed by environmental changes.
To avoid panic due to time differences and sudden swings, objective signals are essential.
