DDMMYYYY is a date notation in which the day is written first, followed by the month and then the year, with the day and month typically shown as two digits and the year as four digits. In everyday use, the digits are often separated by punctuation such as slashes, dots, or hyphens, for example 25/04/2023 or 25-04-2023; sometimes the digits are written contiguously as 25042023.

This format is common in many regions outside North America, including much of Europe, Africa, and parts of Asia, where the day-month-year order reflects local conventions. Readers in different locales may interpret the same numeric string differently if separators are absent or if the regional habit varies. For instance, without clear separators, 01022004 could be read as 1 February 2004 in a DDMMYYYY system or as 2 January 2004 in a MMDDYYYY system.

In computing and international data exchange, unambiguous date representation is often achieved with the ISO 8601 standard, which uses YYYY-MM-DD to prevent confusion across locales. When using DDMMYYYY, it is advisable to include separators and, where possible, to provide a clearly labeled date or to favor ISO formats for interoperable systems.

Examples of the DDMMYYYY format include 25042023 for 25 April 2023 and 01012024 for 1 January 2024. Awareness of regional conventions helps minimize misinterpretation in documentation, forms, and software.
