Since the Philippines has not adopted any time and date representation standard based on the ISO 8601, notation practices across the country are in various, customary formats.

Date
In casual settings, alphanumeric date formats are usually written with a middle-endian order (month-day-year) in a way similar to that of the United States. Another format, the little-endian order (day-month-year), is widely applied in more formal transactions and written communications especially in businesses, the government and academe, also in the military and usually the police, although the middle-endian format is still prevalent in daily use (except the armed forces). Since there is no law mandating the date order, minimum or maximum length, or format (i.e. alphanumeric or numeric), notations sometimes vary from office to office, in private and public sectors. Such can be observed in passports issued by the Department of Foreign Affairs, which particularly notate the date numerically as MM-DD-YY, and in house bills or executive orders dated alphanumerically with a MMMM-DD-YYYY format.
Hyphens (-) and forwardslashes (/) are the most common separators for a numeric date format. On the other hand, an alphanumeric date in month-day-year format instead uses spacing and a comma between the day and year. A 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:
In Filipino, however, the date-month-year notation is the proper format as adapted from the Spanish. The cardinal prefix ika is applied on the day as in ika-31 ng Disyembre, 2015 (English: 31st of December 2015). The month-date-year format is also used, albeit rarely and more for Spanish recitation. The English-based formats (Disyembre 31, 2015 or, especially in the military, 31 Disyembre 2015) are used but are still read in the Filipino date-month-year notation.
Time
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 (e.g. 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.
Spoken Conventions
Numerical elements of dates and the time may pronounced using either their Spanish names or vernacular ones; the former is somewhat pedestrian whilst the latter tends to be longer, formal and academic.
Examples:
Date: 12/15/2015
Time: 8:30 p.m.
