20200515

20200515 is a date expressed in the compact YYYYMMDD format, representing May 15, 2020. It is commonly used in computing, data storage, and archival systems where a sortable, locale-independent representation of a date is advantageous.

The format consists of four-digit year (2020), two-digit month (05), and two-digit day (15) with no separators. It sorts lexicographically in the same order as chronological time. In many contexts, the same date is written as 2020-05-15 in ISO 8601 style; both denote the same calendar day.

In practice, 20200515 may appear in filenames, log entries, database keys, and version-control commits, where compactness and unambiguous ordering are valued. When combined with time information, it can form strings like 20200515T123456Z to indicate a precise moment in Coordinated Universal Time.

The day corresponds to May 15, 2020 on the Gregorian calendar and fell on a Friday. The date occurred during the period of widespread monitoring and responses to the COVID-19 pandemic, with many regions implementing or adjusting public health measures at that time.
