Postal codes come from the free GeoNames dataset. Where a code is listed with a distance, it belongs to a nearby settlement — GeoNames spells that name differently from ours.
Goyang-Si uses the national time observed throughout South Korea. No conversion is needed for domestic meetings, broadcasts, or transport schedules involving Seoul, Busan, or another South Korean city.
For contact with another country, compare its current offset with UTC+9. Some places move their clocks seasonally, causing the time difference to change while Goyang-Si remains on the same offset. Recheck any international appointment arranged well ahead.
Place the city name and date beside a proposed meeting time. Check whether the other location is observing daylight saving time. Watch for conversions that cross into another calendar day. Update recurring schedules when an overseas clock change occurs. A correct time conversion gets everyone to the call; a good agenda helps them escape it.
Sunrise and sunset shift noticeably through the year in Goyang-Si. The changing day length affects commuting light, outdoor recreation, photography, and the time at which evening darkness arrives. Published solar times are calculated for a representative location and a standard horizon. Mountains, apartment buildings, trees, haze, and cloud can change the observed moment. From a street surrounded by tall structures, direct sunlight may appear well after the formal sunrise.
Dawn precedes sunrise and twilight follows sunset, but the available light depends on the sky. A clear evening may remain bright enough for some activities after sunset, whereas thick cloud can make it seem dark sooner. Date-specific values are preferable to estimates remembered from another season.
Goyang-Si experiences distinct seasonal weather, including changes in temperature, humidity, precipitation, wind, and cloud. Current conditions should guide immediate decisions, while an hourly forecast helps match expected changes to a commute or outdoor plan.
Check the apparent temperature before choosing clothing. Review hourly precipitation for the period spent outside. Consider wind when using exposed paths or open spaces. Compare the planned finishing time with sunset and twilight.
Weather can differ between dense urban areas, parks, and more exposed locations. A reading from one observation point is representative rather than universal. Rain or snow may also vary in timing and intensity across the wider Gyeonggi-do area.
When conditions may affect transport, consult current service notices in addition to the forecast. The weather page explains what may happen in the atmosphere; it does not confirm whether a particular road, rail service, or path is operating normally.
