How to Add Dates in MySQL
November 13, 2023
Adding dates in MySQL is a common task for database management, often requiring precision and understanding of MySQL's date and time functions. The DATE_ADD
function, in particular, is essential for manipulating and calculating dates.
Understanding DATE_ADD
The DATE_ADD
function in MySQL is used to add a specified time interval to a date.
Syntax
DATE_ADD(date, INTERVAL expr unit)
date
: The starting dateexpr
: The value of the time interval to addunit
: The unit of the time interval (e.g., DAY, MONTH, YEAR)
Examples of DATE_ADD Usage
Adding Days to a Date
SELECT DATE_ADD('2023-01-01', INTERVAL 10 DAY);
This query adds 10 days to January 1, 2023.
Adding Months to a Date
SELECT DATE_ADD('2023-01-01', INTERVAL 2 MONTH);
This adds 2 months to January 1, 2023.
Adding Years to a Date
SELECT DATE_ADD('2023-01-01', INTERVAL 1 YEAR);
This example adds 1 year to January 1, 2023.
Combining DATE_ADD with Other Functions
Current Date Addition
SELECT DATE_ADD(CURDATE(), INTERVAL 15 DAY);
Adds 15 days to the current date.
Date Subtraction
SELECT DATE_ADD('2023-01-01', INTERVAL -3 DAY);
Subtracts 3 days from January 1, 2023.

Handling Time Components
Adding Hours, Minutes, and Seconds
SELECT DATE_ADD('2023-01-01 08:30:00', INTERVAL '2:15:30' HOUR_SECOND);
Adds 2 hours, 15 minutes, and 30 seconds to the specified datetime.
Advanced DATE_ADD Usage
Adding Complex Intervals
SELECT DATE_ADD('2023-01-01', INTERVAL '1-2' YEAR_MONTH);
Adds 1 year and 2 months to January 1, 2023.
Using DATE_ADD in Table Updates
UPDATE orders SET delivery_date = DATE_ADD(order_date, INTERVAL 7 DAY) WHERE order_id = 1001;
Sets the delivery date to 7 days after the order date for a specific order.
Common Mistakes and Tips
- Ensure the date format matches MySQL's standard YYYY-MM-DD or YYYY-MM-DD HH:MM:SS.
- Be cautious with leap years and month-end dates while adding months or years.
- Use the
DATE_SUB
function for more intuitive date subtraction.
