20230405

20230405 is a numeric date tag using the YYYYMMDD format, representing the calendar date April 5, 2023 in the Gregorian calendar. In ISO 8601 notation, the same date is written with separators as 2023-04-05. The date fell on a Wednesday and was the 95th day of 2023, with the year not being a leap year.

Beyond its role as a single day, 20230405 is commonly used in computing and data management because the YYYYMMDD sequence sorts chronologically when treated as a string and avoids locale-based ambiguity. It is frequently used in file naming, data archives, versioning, log timestamps, and database keys. This format supports straightforward chronological comparisons and is widely adopted in systems requiring compact, unambiguous date representation.

In calendar systems other than the Gregorian, the same numerical date can align with different local conventions. For example, in Japan the year 2023 corresponds to Reiwa 5, so the date could be expressed as Reiwa 5-04-05 in that era’s format. The ISO week date for this day places it in week 14 of 2023, with the day of the week recorded as Wednesday, providing another layer of temporal context for scheduling and analysis.

Overall, 20230405 serves as a compact, unambiguous timestamp widely used across computing, data management, and record-keeping to denote a specific day in 2023.
