The date and time data types have a wide variety of formats to help meet your unique circumstances. When formatting you have three choices: keep the default formats, apply a predefined format, or create a custom format. When you apply a format to a table field, that same format is automatically applied to any form or report control that you subsequ...
Access automatically displays the date and time in the General Date and Long Time formats. The dates appear as, mm/dd/yyyy in the U.S. and as, dd/mm/yyyy outside the U.S. where mm is the month, dd is the day, and yyyy is the year. The time is displayed as, hh:mm:ss AM/PM, where hh is the hour, mm is minutes, and ss is seconds.
These automatic formats for dates and times vary depending on the geographic location specified in the Microsoft Windows Regional and Language Options setting on your computer. For example, in Europe and many parts of Asia, depending on your location, you might see the date and time as 28.11.2018 12:07:12 PM or 28/11/2018 12:07:12 PM. In the United States, you would see 11/28/2018 12:07:12 PM.
It is possible to change these predefined formats by using custom display formats. For example, you can enter a date in a European format such as 28.11.2018, and have the table, form, or report display the value as 11/28/2018. The custom format that you select will not affect how the data is entered or how Access stores that data.
Access automatically provides a certain level of data validation related to date and time formatting. For example, if you enter an invalid date, such as 32.11.2018, a message appears and you would have the option of entering a new value or converting the field from the Date/Time data type to the Text data type. Valid date values range from -657,434 (January 1, 100 A.D.) to 2,958,465 (December 31, 9999 A.D.). Valid time values range from .0 to .9999, or 23:59:59.
When you want to constrain entry of date and time in a specific format, use an input mask. For example, if you applied an input mask to enter dates in the European format, someone entering data in your database will not be able to enter dates in other formats. Input masks can be applied to fields in tables, query result sets, and to controls on forms and reports. For more information, see Control data entry formats with input masks.
