KST ↔ EAT Time Converter

East Africa Time (EAT) is 6h behind Korea Standard Time (KST). For example, when it is 9:00 AM in KST, it is 3:00 AM in EAT. Korea Standard Time runs at UTC+9 while East Africa Time runs at UTC+3. Always confirm with the live converter above since Daylight Saving Time can shift this offset during certain months of the year.

The quickest way is to use the live bidirectional converter at the top of this page — type any time into the KST field and the EAT result appears instantly. For a manual calculation, subtract 6h to the KST time. So noon (12:00 PM) in KST becomes 6:00 AM in EAT. If the result goes past midnight, adjust by ±24 hours and note the day change. The 24-hour table further down this page also covers every hour of the day at a glance.

East Africa Time (EAT) is 6h behind Korea Standard Time (KST). In practical terms, clocks in EAT show an earlier time than clocks in KST. The UTC reference points are UTC+9 for KST and UTC+3 for EAT, giving a net raw difference of 6h behind. Remember this raw figure may shift by ±1h when either zone enters or exits Daylight Saving Time.

Type a time into the EAT field in the bidirectional converter above — it works equally in both directions. Manually, do the reverse: add 6h to the EAT time to get KST. You can also visit the dedicated EAT to KST converter page, which has its own live clocks, full table, and meeting planner for the reverse direction.

Because EAT is 6h behind KST, the ideal scheduling window is wherever both zones overlap within 8:00 AM–6:00 PM local time. Check the meeting hours table above for exact slot recommendations. As a general rule, aim for 8:00 AM–11:00 AM KST time — this typically keeps the EAT side within a reasonable morning or afternoon window. Avoid scheduling calls that land before 7:00 AM or after 8:00 PM in either timezone, as attendance and productivity tend to suffer.

Korea Standard Time (KST) does not observe Daylight Saving Time and stays at a fixed UTC offset year-round. If you are scheduling meetings or deadlines that span a DST transition, always recheck the exact offset using the live converter on this page rather than relying on a fixed-offset table, which will be off by one hour during those periods.

East Africa Time (EAT) does not observe Daylight Saving Time, staying at a fixed offset. The live clocks and bidirectional converter on this page use the IANA timezone database and update automatically the moment DST begins or ends, so you never need to manually account for the seasonal shift.

Korea Standard Time (KST) at UTC+9 covers the following major cities and regions: Seoul, Busan, Incheon, Daegu, Daejeon, Gwangju. Not every locality within a country necessarily follows the same standard time — some regions may use sub-zones or observe different DST rules — so always verify local time when precision matters.

East Africa Time (EAT) at UTC+3 covers the following major cities and regions: Nairobi, Addis Ababa, Dar es Salaam, Kampala, Mogadishu, Kigali. As with any timezone, confirm local rules for areas near geographic or political boundaries, where the observed offset can occasionally differ from the standard definition.

Midnight (12:00 AM / 00:00) in KST corresponds to 6:00 PM in EAT — which falls the previous day. This is generally outside normal business hours for both sides. Use the full 24-hour conversion table on this page to quickly look up any other reference time.

Simple formula: EAT = KST – 6h. Example: 3:00 PM KST → 9:00 AM EAT. If the result exceeds 11:59 PM, subtract 24 hours and add one day; if it goes below 12:00 AM, add 24 hours and subtract one day. This fixed formula is accurate when neither zone is in a DST transition — during transitions, rely on the live converter above.

Korea Standard Time (KST) is at UTC+9 and East Africa Time (EAT) is at UTC+3. UTC (Coordinated Universal Time) is the global timekeeping standard against which all timezone offsets are defined. A positive offset like UTC+5 means the local clock is 5 hours ahead of UTC; a negative offset like UTC-5 means it is 5 hours behind. The net difference between UTC+9 and UTC+3 gives the conversion gap of 6h behind used throughout this page.

The live converter uses your browser's built-in Intl.DateTimeFormat API backed by the IANA timezone database (IANA identifiers: Asia/Seoul for KST, Africa/Nairobi for EAT). This automatically applies DST transitions in real time, making the live clocks and converter highly accurate. The static 24-hour table uses fixed offsets and may differ by ±1 hour during DST periods — always prefer the live converter for critical scheduling.
