U+33FD "㏽" Ideographic Telegraph Symbol for Day Thirty Unicode Character
Unicode Version 17.0
㏽
U+33FD "㏽" Ideographic Telegraph Symbol for Day Thirty is a specific visual token from the CJK Compatibility block, originally developed for Japanese telegraph code systems in the late 19th and early 20th centuries to efficiently transmit calendar dates. This symbol represents the thirtieth day of a month, functioning as a compact ideographic representation rather than a numeric one, and it is composed of the characters for "thirty" and "day" in a single square block. Today, this character is rarely used in modern digital communication but persists in Unicode for compatibility with older encoded text, serving as a historical artifact of early telecommunication standards in East Asia.
