The Korean Calendar is a traditional lunar calendar used in South Korea, which is based on the cycles of the moon. It consists of 12 months, with each month beginning on the new moon. This calendar is important for determining traditional holidays and festivals, such as Seollal (Lunar New Year) and Chuseok (Harvest Festival). In addition to the lunar months, the Korean Calendar also incorporates a solar calendar, which is used for everyday purposes. The solar calendar aligns with the Gregorian calendar, making it easier for people to plan events and activities throughout the year.
