KST-SGT Time Converter

Korea Standard Time (KST) 🇰🇷	Singapore Time (SGT) 🇸🇬
🇰🇷 South Korea 🇰🇵 North Korea	🇸🇬 Singapore

Why you'd want this tool in your pocket

Korea and Singapore might only be one hour apart, but juggling schedules across time zones can still lead to confusion—especially when you’re dealing with early flights, tight meetings, or overlapping working hours. This converter takes away the guesswork by letting you plug in a date and time, and instantly seeing what that looks like on the other end.

How it works behind the scenes

The converter takes your chosen date and time and adjusts it based on whether you’re starting with Korea or Singapore time. You can switch between the two with the “Swap” button, and there’s a “Now” button that fills in the current local time for a quick check. Because both countries stick to fixed UTC offsets—Korea at UTC+9 and Singapore at UTC+8—the result is always precise and consistent.

Step-by-step: Using the KST-SGT time converter

1. Choose the starting time zone

The top section lets you pick whether you're starting from Korea Standard Time or Singapore Time. The drop-down is labeled clearly, and once you select your zone, it updates the titles and conversion flow accordingly.

2. Pick the date and time

Select a date and enter the time you’re starting with. If you’re unsure of the current time in your location, hit “Now” to auto-fill it based on the selected zone.

3. Click “Convert Time”

You’ll see the exact converted time on the other side along with a breakdown: UTC offsets, time difference (always 1 hour), and formatted results for both zones.

4. Use live time tracking

The bottom section displays live clocks for KST and SGT, refreshing every second. It helps you stay updated in real time while planning or communicating.

Small features that make a big difference

Auto Convert

When enabled, the tool converts automatically as soon as you change the date or time—no extra button clicks needed. It's great for quick comparisons or adjusting schedules on the fly.

Daylight Saving Aware

This box is on by default, but it mostly applies to other zone pairings. Since neither Korea nor Singapore uses daylight saving time, the difference here remains steady all year round.

UTC Offset Visibility

If you want to see the UTC offset in full format like +09:00 or +08:00, check “Show UTC Offset.” Otherwise, it keeps it clean and simple.

Seconds and Time Format

Want to get down to the second? “Show Seconds” keeps the precision high. You can also toggle between 12-hour and 24-hour formats depending on what you're used to.

What to watch out for

If your converted time reads as "--:--:--", make sure you've selected both a valid date and time. Also, while the “Swap” feature updates both input and output titles, it doesn’t change the selected value in the drop-down unless clicked again—just something to be aware of.

Keyboard shortcuts are also supported. Tap “Enter” to convert, “S” to swap zones, “N” for now, and “R” to reset. It’s a smart little feature if you’re on a laptop and moving quickly.

No more timezone mishaps when coordinating across two busy capitals.
