About
The character 闰, or 閏 in traditional form, combines the gate radical 门 with the internal component 王 (king). This structure reflects an ancient ritual where the king would remain at the palace gateway during an intercalary month instead of holding court, a practice meant to reconcile the lunar calendar with the solar year. From this, the character acquired the meaning of an intercalary or leap period, such as a leap day or month, signifying the calendar adjustment needed to keep seasonal events aligned with the Earth's orbit.
