Frequently Asked Questions
What is the difference between the solar and lunar calendar?โผ
The solar (Gregorian) calendar is based on Earth's orbit around the Sun (365.25 days/year). The lunar calendar is based on Moon phases (about 354 days/year). To keep the lunar calendar aligned with seasons, leap months are added approximately every 3 years.
When is Seollal (Korean New Year) and Chuseok in the solar calendar?โผ
Seollal falls on the 1st day of the 1st lunar month (usually late January to mid-February). Chuseok falls on the 15th day of the 8th lunar month (usually September to early October). The exact solar dates change every year โ use this converter to find them.
What is a Gapja (์ฒ๊ฐ์ง์ง) and how does the 60-year cycle work?โผ
Gapja combines 10 Heavenly Stems (์ฒ๊ฐ) and 12 Earthly Branches (์ง์ง/Chinese zodiac animals) to create a 60-year cycle. Each year has a unique combination (e.g., Gapja ๊ฐ์, Eulchuk ์์ถ). This is why the 60th birthday (Hwangap) celebrates completing one full cycle.
