US market hours for Lagos time na 14:30 go 21:00 WAT for di regular session wen America still dey on summer clock, and e shift to 15:30 go 22:00 WAT from di first week of November. Lagos own clock no dey move at all: WAT na UTC+1 for di whole twelve month, no spring forward, no fall back. So any shift wey you see inside di timetable below dey come from di American side alone, no be from your side.

Wetin be US market hours for Lagos time?

Di US trading day get three part, and di part wey people dey call "di market" na only di middle one. Premarket na di early window wey some broker dey open before di opening bell. Regular session na di main one, from di opening bell go di closing bell, and dat na where di closing price come from. Afta-hours na di extra window wey dey run afta di closing bell.

Wen America dey on daylight saving (dat one cover today, 3 October 2026, go 1 November 2026, den e start again 14 March 2027):

• Premarket: 09:00 WAT go 14:30 WAT
• Regular session: 14:30 WAT go 21:00 WAT
• Afta-hours: 21:00 WAT go 01:00 WAT di next morning

Wen America go back to standard time (2 November 2026 go 12 March 2027):

• Premarket: 10:00 WAT go 15:30 WAT
• Regular session: 15:30 WAT go 22:00 WAT
• Afta-hours: 22:00 WAT go 02:00 WAT di next morning

Di premarket window dey start 4:00 a.m. New York time and di afta-hours window dey end 8:00 p.m. New York time, but no every broker dey hand you di full stretch, plenty of dem dey open later and close earlier. Di session-by-session breakdown dey inside our US stock market hours guide, and di rule for di extended window dey inside premarket and afta-hours trading.

Di two clock-change date for 2026 and 2027

America dey end daylight saving di first Sunday of November and dey start am back di second Sunday of March. For dis cycle, dat na Sunday 1 November 2026 and Sunday 14 March 2027. Di clock dey move 2 a.m. local time on di Sunday, so di first session wey you go really feel am na Monday 2 November 2026, wen everything shift one hour late for Lagos, and Monday 15 March 2027, wen everything shift one hour back early. Two Monday for di year, dat na all. Di longer version dey inside daylight saving and US market hours.
