Lunar-Solar Calendar Converter (음력 양력 변환기)
Convert between Korean/Chinese lunar calendar and Gregorian solar calendar (1900-2050).
Overview
The Korean and Chinese lunisolar calendar tracks the moon for months and the sun for years. An ordinary year of twelve lunar months runs about 354 days, eleven short of the solar year, so an intercalary month (윤달) is inserted roughly seven times every nineteen years to keep the calendar aligned with the seasons. A lunar date therefore drifts against the Gregorian calendar by about eleven days annually before jumping back.

About
Conversion between the two is a lookup rather than a formula. Month lengths of 29 or 30 days and the placement of leap months are determined by astronomical new moons and solar terms observed at a reference meridian, so a table of computed values covering 1900 to 2050 is the practical basis for any conversion in that range.
Each lunar year also carries a zodiac animal from a twelve-year cycle and a sexagenary designation from the sixty-term stem-and-branch cycle, both of which turn over at lunar new year rather than on 1 January.
