SGT to EDT Time Converter
Eastern Daylight Time (EDT) is currently 12 hours behind Singapore Time (SGT). SGT is UTC+8 and EDT is UTC-4. The table below converts every hour of the day between the two, and the call planner shows where working hours line up.
Best Time for a Call
There is no overlap between 9:00 AM and 5:00 PM office hours in these two zones. Stretching to early mornings and evenings, the workable window runs from 7:00 PM to 9:00 PM in SGT, which is 7:00 AM to 9:00 AM in EDT. One side ends up outside normal hours, so alternating who takes the awkward slot is a fair way to handle recurring calls.
