When it is 09:00 in Singapore it is 04:00 in Istanbul in January and 04:00 in July. Istanbul is 5 hours behind Singapore right now — and the difference is the same all year. This page gives the live times in both cities, the overlap between their working days, the daylight saving dates that move the difference, and the best meeting windows.

Live times in Singapore and Istanbul
The two cities side by side. The January column uses the winter offsets (Singapore UTC+08:00, Istanbul UTC+03:00); the July column uses the summer offsets (Singapore UTC+08:00, Istanbul UTC+03:00).

The world clock shows the current time in both cities live, and the individual city pages — time in Singapore and time in Istanbul — explain each city's time zone, offsets and daylight saving in full.
The time difference between Singapore and Istanbul
The difference is constant: Istanbul is 5 hours behind Singapore on every day of the year. That is the simplest case in time-zone work — the answer does not depend on the date, and a meeting set for 09:00 in Singapore is always 04:00 in Istanbul. The reason the difference never changes is that neither city observes daylight saving.
To convert a time, add the difference: 09:00 in Singapore is 04:00 in Istanbul in January and 04:00 in July; 17:00 in Singapore — the end of the working day — is 12:00 in Istanbul in January and 12:00 in July. To go the other way, subtract it: 09:00 in Istanbul is 14:00 in Singapore in January. The time difference calculator does the arithmetic for any date, and the UTC to Istanbul page gives the full conversion table for Istanbul.
Meeting overlap between Singapore and Istanbul
The overlap is the hours when both cities are in their working day (09:00–17:00 local time). The table marks the overlapping hours in Singapore's working day and shows what time they are in Istanbul.
January
| Singapore time | Istanbul time | Both working? |
|---|---|---|
| 09:00 | 04:00 | No |
| 10:00 | 05:00 | No |
| 11:00 | 06:00 | No |
| 12:00 | 07:00 | No |
| 13:00 | 08:00 | No |
| 14:00 | 09:00 | No |
| 15:00 | 10:00 | No |
| 16:00 | 11:00 | No |
In January the overlap is 0 hours: there is no hour when both cities are in their working day. In July it is 0 hours: there is no hour when both cities are in their working day. The two working days do not overlap at all — the difference is too large. The only options are to meet at the edge of the day, to rotate the awkward hour, or to record the meeting.
Daylight saving in Singapore and Istanbul
Singapore does not observe daylight saving, so its offset of UTC+08:00 never changes.
Istanbul does not observe daylight saving, so its offset of UTC+03:00 never changes.
The difference never changes, so there is no date on which a standing meeting moves. That does not mean the difference is the same as the difference with a third city — the difference between Singapore and London, for example, may still move when London changes its clocks. The individual DST pages — Singapore DST 2026 and Istanbul DST 2026 — give the exact dates for each city.
Best meeting windows
There is no window inside both working days, in January or in July. The least-bad options are the edges: 08:00 in Singapore is 03:00 in Istanbul in January — before the working day in Singapore but a reasonable evening in Istanbul — and 17:00 in Singapore is 12:00 in Istanbul, which is the morning in Istanbul the next day if the difference is large. Rotate the early start between the two sides, week by week, so the same people are not always the ones getting up early.
Calling and travel notes
When it is 09:00 in Singapore it is 04:00 in Istanbul in January; when it is 12:00 in Singapore it is 07:00 in Istanbul; when it is 17:00 in Singapore it is 12:00 in Istanbul. The difference is under 12 hours, so the two cities are usually on the same date — but check the date for late-evening and early-morning times, when the date can differ by a day. Scheduling between Asia and Europe works best in the late morning in Istanbul and the afternoon or evening in Singapore. The difference is 5–9 hours, so the overlap is a few hours in the middle of the day. The main trap is daylight saving: Europe changes its clocks twice a year, and most of Asia does not, so the difference — and the overlap — moves by an hour in March and October.

The table is the whole pair in one place. The two numbers that matter most are the January and July offsets: if they are the same in both columns for a city, that city's offset never changes; if they differ, the city observes daylight saving and the difference between the cities moves with it. The individual city pages — time in Singapore and time in Istanbul — explain each city's time zone, and the DST pages — Singapore DST 2026 and Istanbul DST 2026 — give the exact change dates.
Frequently asked questions
What is the time difference between Singapore and Istanbul?
Istanbul is 5 hours behind Singapore right now. In January the difference is 5 hours behind and in July it is 5 hours behind — it is the same all year.
How do I schedule a recurring meeting between Singapore and Istanbul?
Pick a time inside the overlap — the edge of the day, since there is no overlap — and set the calendar event in UTC so it moves correctly when the clocks change. Re-check the overlap in March and October, when the difference moves, and rotate the time if the meeting falls outside someone's working day.
What time is it in Istanbul when it is 09:00 in Singapore?
It is 04:00 in January and 04:00 in July. The time zone converter gives the answer for any date.
What is the best time for a meeting between Singapore and Istanbul?
There is no hour inside both working days. Meet at the edge of the day — early morning in one city, evening in the other — and rotate the awkward hour.
Does the time difference between Singapore and Istanbul change during the year?
No. The difference is 5 hours behind all year, because neither city observes daylight saving.
What time is it in Singapore when it is 09:00 in Istanbul?
It is 14:00 in January and 14:00 in July. See Istanbul to Singapore time for the full comparison from Istanbul's side.
What are the time zones of Singapore and Istanbul?

What time is it in Singapore when it is midnight in Istanbul?
It is 05:00 in Singapore in January and 05:00 in July — the previous day, because Istanbul is ahead of Singapore. Midnight conversions are the ones that most often land on the wrong date, so always check the date as well as the time.
