0230

0230 is a four‑digit sequence that can function as a numeric label or as a notation with a leading zero. In decimal, the number is 230; in programming languages that treat a leading zero as indicating an octal literal, 0230 stands for decimal 152.

0230 is commonly used in time notation in 24-hour clocks to denote 02:30, i.e., two thirty in the morning. In scheduling or timetables, it may indicate early-morning events or file creation times. In computing contexts, a four-digit code such as 0230 can function as an identifier within systems that require fixed-width fields, where its meaning depends on the specific schema or software.

As a year, 0230 refers to 230 CE in the Julian calendar. Historical references from that era would be contextual to the Roman Empire and the broader regional dynamics of late antiquity, but the exact events attributable to that year depend on regional sources and scholarly interpretation.
