U+3370 "㍰" Ideographic Telegraph Symbol for Hour Twenty-Four is a single compact glyph used in East Asian telegraph coding systems to represent the time 24:00 or midnight, functioning as a shorthand for the ideographic expression for the 24th hour of the day. This character belongs to a larger set of CJK compatibility ideographs originally designed for telecommunication equipment, where each symbol encodes a specific time in a standardized format.
