Frequently Asked Questions
What information does this page show?
The day detail page lists every Singapore public holiday recorded on this date, the day position within the calendar year, and the Western zodiac sign plus Chinese zodiac (shio) for the date.
How is the Chinese lunar date on this page computed?
The Chinese lunar date follows standard astronomical rules. A new lunar month begins on the day containing the astronomical new moon as seen from the 120°E meridian (China Standard Time, UTC+8). Leap months are inserted when a lunar year contains 13 lunations without a zhongqi (major solar term). The day pillar and sexagenary year pillar use the traditional ganzhi cycle. This calculation matches the official reference used for Chinese New Year and lunar festivals in Singapore.
How is the moon phase information computed?
The moon's illumination percentage, lunar age (0 to 29.5 days), and the four principal phases (new moon, first quarter, full moon, last quarter) are calculated using standard astronomical algorithms and shown in Singapore Time (SGT, UTC+8). Moonrise and moonset times are computed for Singapore's latitude and longitude. Values are typically accurate to within a few minutes of published ephemerides.
How is the Chinese zodiac (shio) calculated here?
The shio is computed from the Gregorian year with a simple formula and is NOT adjusted for Chinese New Year, which falls between 21 January and 20 February. For dates before Chinese New Year, the shio technically still belongs to the previous zodiac year.
What is the difference between zodiac and shio?
Western zodiac divides the solar year into 12 star signs based on your date of birth, while shio (Chinese zodiac) divides a 12-year cycle into animal signs. Zodiac changes each month, shio changes each year.
