🌤️ Daylight Saving Time (DST) Explained

EST (Eastern Standard Time) observes Daylight Saving Time (DST), shifting clocks forward by one hour during summer months. EAT (East Africa Time) does not observe DST and stays fixed at UTC+3 year-round. This means the time difference between the two zones changes seasonally — the gap narrows by one hour when EST moves to its daylight variant. The live converter and clocks on this page detect the current offset automatically, so you always get the correct result without manually tracking DST transitions.
