Frequently Asked Questions
How do I read the Chinese lunar dates on this calendar?
Chinese lunar days appear as small orange numbers in the bottom-left corner of each day cell. On the first day of a new lunar month, the day number is replaced by the Chinese month label (for example 正月 for the first month, 二月 for the second). The lunar calendar is computed astronomically using the 120°E meridian (China Standard Time), which is the official reference for the traditional Chinese calendar. A small orange dot below a date marks a traditional Chinese observance such as Lunar New Year, Qingming, or the Mid-Autumn Festival.
How accurate are the moon phases shown?
The four principal moon phases (new moon, first quarter, full moon, and last quarter) are computed using standard astronomical algorithms and displayed in Singapore Time (SGT, UTC+8). Phase times are typically accurate to within a few minutes of published ephemerides.
