                    SELECT DATE_ADD(date, INTERVAL expr unit);

Parameters

1. date | date/datetime

The date / datetime to add the time interval to.

2. expr unit | integer with units

The interval to add to the provided date together with its units.

Refer to 'List of units' at the bottom of page for a valid list of units.

Return value

Examples

Consider the following table about some students:

student_id	fname	lname	day_enrolled	age	username
1	Sky	Towner	2015-12-03	17	stowner1
2	Ben	Davis	2016-04-20	19	bdavis2
3	Travis	Apple	2018-08-14	18	tapple3
4	Arthur	David	2016-04-01	16	adavid4
5	Benjamin	Town	2014-01-01	17	btown5

The above sample table can be created using the code here.

Basic usage

To add 2 days to student enrollment dates:


        
        
            
                
                
                    SELECT fname, day_enrolled, DATE_ADD(day_enrolled, INTERVAL 2 DAY)
FROM students;
                
            
            +----------+--------------+----------------------------------------+
| fname    | day_enrolled | DATE_ADD(day_enrolled, INTERVAL 2 DAY) |
+----------+--------------+----------------------------------------+
| Sky      | 2015-12-03   | 2015-12-05                             |
| Ben      | 2016-04-20   | 2016-04-22                             |
| Travis   | 2018-08-14   | 2018-08-16                             |
| Arthur   | 2016-04-01   | 2016-04-03                             |
| Benjamin | 2014-01-01   | 2014-01-03                             |
+----------+--------------+----------------------------------------+

To add 2 months to student enrollment dates:


        
        
            
                
                
                    SELECT fname, day_enrolled, DATE_ADD(day_enrolled, INTERVAL 2 MONTH)
FROM students;
                
            
            +----------+--------------+------------------------------------------+
| fname    | day_enrolled | DATE_ADD(day_enrolled, INTERVAL 2 MONTH) |
+----------+--------------+------------------------------------------+
| Sky      | 2015-12-03   | 2016-02-03                               |
| Ben      | 2016-04-20   | 2016-06-20                               |
| Travis   | 2018-08-14   | 2018-10-14                               |
| Arthur   | 2016-04-01   | 2016-06-01                               |
| Benjamin | 2014-01-01   | 2014-03-01                               |
+----------+--------------+------------------------------------------+

Negative intervals

To subtract 1 day from a date:


        
        
            
                
                
                    SELECT DATE_ADD('2020-01-01', INTERVAL -1 DAY);
                
            
            +-----------------------------------------+
| DATE_ADD('2020-01-01', INTERVAL -1 DAY) |
+-----------------------------------------+
| 2019-12-31                              |
+-----------------------------------------+

Note that there is a separate method DATE_SUB(~) specifically for subtracting intervals from a date / datetime.
