What is the time difference between Atlantic Standard Time and Singapore?

What's the best time for a call between Atlantic Standard Time and Singapore?
There's no comfortable 9-to-5 overlap between Atlantic Standard Time and Singapore — they sit on opposite sides of the planet's working day. Plan for an early or late call on one side, or hand work off asynchronously.
Does this account for daylight saving time?
Yes. We track every clock change in both places, so the abbreviations you see — ADT and +08:00 — are the ones actually in effect right now, not a fixed all-year value. When either side changes its clocks, this page updates automatically.
Why is the date sometimes different on each side?
When two places are far enough apart, the same moment can fall on different calendar days. That is why some conversions are marked "previous day" or "next day" — it is the same instant in time, read off two clocks that crossed midnight at different points.
