The best windows to reach Singapore.
Four factors that decide when a Singaporean prospect picks up — across the single SGT business day.
Singapore runs at +08:00
The zone is Asia/Singapore. Every window on this page is worked out from that offset rather than a rule of thumb, so the times shown are the ones that actually apply to Singapore.
No daylight saving
Singapore stays on +08:00 all year. The windows below only move when the caller's own country changes its clocks, not when Singapore does.
