London to Singapore Time Converter

Realistic Overlap for a Standard 9-to-5

Assuming a standard 9am–5pm workday on both ends, London and Singapore share about 0–1 hours of true overlap. That's a narrow window, tight enough that it's worth protecting deliberately (a fixed daily or twice-weekly slot) rather than assuming it'll happen organically.

• January: the one-hour slot that splits the inconvenience most evenly is 8:30am in London = 4:30pm in Singapore.
• July: the shared window is 9:00am–10:00am in London = 4:00pm–5:00pm in Singapore.

• Jan 1 — Singapore is 8 hours ahead of London.
• Mar 29 — London springs forward to UTC+1, so Singapore is now 7 hours ahead of London.
• Oct 25 — London falls back to UTC+0, so Singapore is now 8 hours ahead of London.
