Two historical markers with varying date formats in Filipino (left, using MDY format) and English (right, using both MDY and DMY formats).

Date and time notation in the Philippines varies across the country in various, customary formats. Some government agencies in the Philippines have adopted time and date representation standard based on the ISO 8601, notably the Philippines driver's license and the Unified Multi-Purpose ID.

In casual settings, as a legacy of American rule in the early 20th century, alphanumeric date formats are usually written with a middle-endian order (month-day-year) in a way similar to that of the United States.^[1] Another format, the little-endian order (day-month-year), similar way to that of United Kingdom, ^{[citation needed]} is applied primarily by the military and the police, although it is also used for more formal civil uses such as government memorandums, a number of tertiary-level educational institutions such as the University of the Philippines system, and business databases for companies that deal with non-East Asian clients. Other minor applications of the little-endian format include certificates, plaques, trophies and expiration dates.^[2]

There is no law mandating the date order, minimum or maximum length, or format (i.e. alphanumeric or numeric), and notations sometimes vary from office to office, in private and public sectors. For example, passports issued by the Department of Foreign Affairs, which particularly notates the date alphanumerically as DD-MMM-YYYY, legislative bills and executive orders are dated alphanumerically with a MMMM-DD-YYYY format. The little-endian (day-month-year) date format is always written alphanumerically by default to avoid confusion. Driver's license issued by the Land Transportation Office and the UMID issued by the Social Security System, Government Service Insurance System, Philippine Health Insurance Corporation, and Home Development Mutual Fund uses the ISO 8601 standard and notates the date numerically as YYYY-MM-DD.

Hyphens (-) and forwardlashes (/) are the most common separators for a numeric date format. The use of periods (.) are almost exclusively used for expiration dates that are normally written in the alphanumeric day-month-year format. On the other hand, an alphanumeric date in month-day-year format instead uses spacing and a comma between the day and year. The day-month-year variant likewise does not necessarily require a comma between the month and year.

Below are date format variations typically used in the Philippines:

Standard: November 16, 2024 or month day, year. Is the most common date format being use by the Filipino people in general.(refresh)

The following date format variations are less commonly used:

In Tagalog and Filipino, however, the day-month-year notation is the format as adapted from the Spanish. The ordinal prefix ika is applied on the day first as in ika-4 ng Enero, 2021 (English: 4 January 2021). The month-day-year format is also used, albeit rarely and more for Spanish recitation. ^{[citation needed]} The English-based formats (Enero 4, 2021 or increasingly in the government, 4 Enero 2021) are used but are still read in the Tagalog day-month-year notation.

The Philippines uses the 12-hour clock format in most oral or written communication, whether formal or informal. A colon (:) is used to separate the hour from the minutes (12:30 p.m.). The use of the 24-hour clock is usually restricted in use among airports, the military, police and other technical purposes.

Numerical elements of dates and the time may pronounced using either their Spanish names or vernacular ones; the former is somewhat pedestrian while the latter tends to be longer, formal and academic.
