Date and time notation in the Philippines

Date notation in the Philippines varies across casual and formal settings. In informal contexts, the month-day-year format (e.g., January 31, 2025) is commonly used due to historical American influence. The military and police primarily use the day-month-year format (e.g., 31 January 2025), also adopted by government agencies like立法 bills and executive orders. Numeric dates often use hyphens or slashes as separators, while periods are reserved for expiration dates in alphanumeric formats. Alphanumeric month-day-year formats typically include spaces and commas.

The ISO 8601 standard (YYYY-MM-DD) is used by entities such as driver's licenses and the Unified Multi-Purpose ID. In Tagalog and Filipino, the day-month-year format with the "ika" prefix is prevalent (e.g., ika-4 ng Enero, 2021 for January 4, 2021).

Time notation primarily follows the 12-hour clock format (e.g., 8:30 p.m.), separated by a colon. The 24-hour format is limited to technical uses like airports and military operations.

Oral communication often mixes Spanish-derived terms with Tagalog or English equivalents. For example, dates and times are pronounced using Spanish names (e.g., "Alas otso y medya ng gabi" for 8:30 p.m.) alongside English or vernacular alternatives.
