19750320

19750320 is the eight-digit numeric date commonly used to represent March 20, 1975, in the Gregorian calendar. It is a compact form of the date often employed in computing, data storage, and file naming to avoid separators and to facilitate sorting.

In practice, the format YYYYMMDD places the year first, followed by the month and day, which allows straightforward lexicographical ordering to correspond to chronological order. This compact representation is widely used in databases, version control, and other information systems, and it is compatible with the broader principle of using a year-month-day sequence as a stable, unambiguous date notation. While ISO 8601 standardizes the YYYY-MM-DD form, many systems also adopt the contiguous YYYYMMDD variant for practical purposes.

Historically, 19750320 does not have a single globally recognized event universally tied to it. It falls within a period of global change in the mid-1970s, but any specific occurrences on that exact date would be particular to a region, institution, or field and are not implied by the date notation itself.
