What Data Type Is Time in Access?

When working with databases in Microsoft Access, it is essential to understand the different data types available for storing various types of information. One common data type that often causes confusion is the Time data type.

The Time Data Type

The Time data type in Microsoft Access is specifically designed to store time values. It allows you to represent a specific point in time, such as the current time or a specific time of day.


  • The Time data type follows a 24-hour clock format.
  • The format is HH:MM:SS, where HH represents hours, MM represents minutes, and SS represents seconds.
  • You can include milliseconds by using the format HH:MM:SS.mmm.

Working with the Time Data Type

When working with the Time data type in Access, you can perform various operations and calculations. Here are some important points to keep in mind:

1. Entering Time Values

To enter a time value into an Access database, you can simply input it in the desired format directly into a field with the Time data type. For example, if you want to enter 9:30 AM, you can directly input “09:30:00” into the field.

2. Displaying Time Values

To display time values stored in an Access database properly, you can use formatting options. For example, you can use the “Short Time” or “Long Time” formats to display only the time portion or include additional information such as AM/PM.

3. Mathematical Operations

You can perform mathematical operations on Time data type fields in Access. For example, you can add or subtract time values, calculate the difference between two time values, or compare time values to determine if one is greater than or less than another.


The Time data type in Microsoft Access provides a reliable way to store and manipulate time values within a database. By understanding its format and how to work with it, you can effectively manage time-related information in your Access applications.
