EST ↔ SGT Time Converter

Singapore Standard Time (SGT) is 13h ahead of Eastern Standard Time (EST). The offset comes from EST being at UTC-5 / UTC-4 (EDT) and SGT at UTC+8. For example, when it is 9:00 AM in New York, it is 10:00 PM in Singapore.

To convert EST to SGT, add 13 hours to the EST time. For instance, 12:00 PM EST becomes 1:00 AM SGT. For times that cross midnight, remember to adjust the date accordingly — a "+1 Day" or "-1 Day" note in the converter above flags this automatically. You can also just type directly into the converter fields on this page for instant results.

Singapore Standard Time (SGT) is 13h ahead of Eastern Standard Time (EST). Put the other way, EST is 13h behind of SGT. If someone in Singapore says "let's meet at noon," that translates to 11:00 PM in New York.

Eastern Standard Time (EST) is the standard clock time used in regions including New York, Washington DC, Boston, Atlanta. It runs at UTC-5 / UTC-4 (EDT) relative to Coordinated Universal Time (UTC). It observes Daylight Saving Time, advancing clocks by one hour during summer, so the effective offset changes seasonally.

Singapore Standard Time (SGT) is the standard clock time used in regions including Singapore, Kuala Lumpur, Penang, Johor Bahru. It runs at UTC+8 relative to Coordinated Universal Time (UTC). It does not observe Daylight Saving Time, so the offset stays fixed all year.

The best window for meetings between EST and SGT is when standard business hours (9 AM – 6 PM) overlap in both zones. Given that SGT is 13h ahead of EST, mornings in the earlier zone tend to align with afternoons in the later zone. Refer to the meeting hours table above to find the exact windows that fall within working hours for both sides. Avoid scheduling calls where one side falls before 7 AM or after 9 PM — those hours are shaded in the table.

Simply type a time into the SGT field in the bidirectional converter above — it works equally well in both directions and updates the EST result instantly. Alternatively, subtract 13 hours from the SGT time to get the EST equivalent. You can also visit the reverse page: SGT to EST converter.

Yes, for some hours they do. Whenever a converted time crosses midnight, the converter above displays a "+1 Day" or "-1 Day" indicator next to the result. The 24-hour table on this page also shows the day change in the Day column. Always check this when scheduling across these two zones to avoid date confusion in calendar invites.

Eastern Standard Time (EST) is used by cities and regions including: New York, Washington DC, Boston, Atlanta, Miami, Philadelphia, Toronto. The zone covers UTC-5 / UTC-4 (EDT)and shifts during Daylight Saving Time.

Singapore Standard Time (SGT) is observed in cities and regions including: Singapore, Kuala Lumpur, Penang, Johor Bahru, George Town, Ipoh, Kuching. It runs at UTC+8, remaining constant throughout the year.

Yes. EST observes Daylight Saving Time and shifts clocks by one hour seasonally. When only one zone is in DST, the gap between the two changes by one hour. The live clocks and converter on this page use the IANA timezone database and adjust automatically, so you always see the current accurate offset without needing to track DST manually.
