Does SQLite Have a Date Data Type?


Heather Bennett

SQLite is a popular and widely used database engine that is known for its simplicity, reliability, and efficiency. It offers a wide range of data types to store different types of data, including integers, floating-point numbers, text, and blobs. However, one common question that arises when working with SQLite is whether it has a specific data type to handle dates.

SQLite Date Data Type

Unlike some other database management systems, such as MySQL or PostgreSQL, SQLite does not have a dedicated date data type. Instead, it provides several other data types that can be used to store and manipulate dates and times.

1. TEXT Data Type

The most common approach to store dates in SQLite is by using the TEXT data type. Dates can be represented as strings in a specific format such as “YYYY-MM-DD” or “YYYY-MM-DD HH:MM:SS”. This format ensures consistency and allows for easy sorting and comparison of dates.

To insert a date into a column with the TEXT data type, you can use the following syntax:

INSERT INTO table_name (date_column) VALUES (‘YYYY-MM-DD’);

Note: Make sure to enclose the date value in single quotes.

2. INTEGER Data Type

Another approach is to use the INTEGER data type to store dates as Unix timestamps. A Unix timestamp represents the number of seconds elapsed since January 1st, 1970 UTC. Storing dates as integers allows for efficient calculations and comparisons using built-in SQLite functions.

To insert a date into an INTEGER column, you need to convert it into a Unix timestamp using programming language-specific functions or SQLite’s built-in strftime() function:

INSERT INTO table_name (date_column) VALUES (strftime(‘%s’, ‘YYYY-MM-DD’));

Note: The strftime() function formats the date as a Unix timestamp.

Working with Dates in SQLite

While SQLite does not have a specific date data type, it offers a variety of built-in functions to manipulate and perform calculations on dates stored as TEXT or INTEGER. Here are some commonly used functions:

Date and Time Functions

  • date(): Extracts the date part from a column or expression.
  • time(): Extracts the time part from a column or expression.
  • datetime(): Converts a string or numeric value into a datetime value.
  • julianday(): Calculates the Julian day number for a given date.
  • strftime(): Formats a datetime value based on the given format string.

Date Calculations

  • DATE(), DATETIME(), and TIMESTAMP(): Converts strings into dates or timestamps based on their formats.
  • CURRENT_DATE, CURRENT_TIME, and CURRENT_TIMESTAMP: Returns the current date, time, or both.
  • +/- operators: Allows addition or subtraction of days, hours, minutes, etc., from a date or timestamp value.

All these functions can be used to perform various operations on dates stored as TEXT or INTEGER values in SQLite.


In summary, SQLite does not have a specific date data type. Instead, it offers the flexibility to store dates as TEXT or INTEGER values. By using the appropriate data type and taking advantage of SQLite’s built-in date and time functions, you can effectively work with dates in your SQLite databases.

Remember to choose the data type that best suits your requirements and consider the trade-offs between simplicity, efficiency, and ease of use when working with dates in SQLite.
