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, ADDDATE(day_enrolled, 2)
FROM students;
+----------+--------------+--------------------------+
| fname | day_enrolled | ADDDATE(day_enrolled, 2) |
+----------+--------------+--------------------------+
| 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, ADDDATE(day_enrolled, INTERVAL 2 MONTH)
FROM students;
+----------+--------------+-----------------------------------------+
| fname | day_enrolled | ADDDATE(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 ADDDATE('2020-01-01', -1);
+---------------------------+
| ADDDATE('2020-01-01', -1) |
+---------------------------+
| 2019-12-31 |
+---------------------------+

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