MySQL YEARWEEK() Function Examples – MySQL

In this MySQL Tutorial, we would love to share with you how to use of MySQL YEARWEEK() function with different examples.


The MySQL YEARWEEK() function is used to returns the year and week for a given date. If you pass the date into the YEAR WEEK function, it will return the result.

You also have the option of specifying whether the week is to start on Sunday or Monday and should be in the range of 0 to 53 or 1 to 53, or not.


Here is YEARWEEK() function syntax:



  • The date is the date you want the number of weeks and weeks to come back from you.
  • Mode is a number that specifies whether the week should start on Sunday or Monday, and weeks should be 53 or 1 to 53. See the table below for possible mode values.

If you do not specify the mode, the mode is 0.


Now we take an example to demonstrate.

SELECT YEARWEEK('2025-01-02') As 'Result';


| Result |
| 202452 |


Next, we take different date example.

SELECT YEARWEEK('1975-10-15') As 'Result';


| Result |
| 197541 |

Example-3 with Specify a Mode

However, you also have the option to present a second argument that you use the mode.

SELECT YEARWEEK('2020-12-10', 5) AS 'Mode 5';


| Mode 5 |
| 202049 |

Below we are providing the list of mode values.

Mode First day of week Range Week 1 is the first week …
0 Sunday 0-53 with a Sunday in this year
1 Monday 0-53 with 4 or more days this year
2 Sunday 1-53 with a Sunday in this year
3 Monday 1-53 with 4 or more days this year
4 Sunday 0-53 with 4 or more days this year
5 Monday 0-53 with a Monday in this year
6 Sunday 1-53 with 4 or more days this year
7 Monday 1-53 with a Monday in this year

These are the same values ??that can be used with the WEEK () function.

Example-4 | Current Date/Time

Let’s take another example , extracting part of the year and week from the current date and time (which is now returned using the () function).



| NOW()               | YEARWEEK(NOW())    |
| 2019-07-10 18:30:44 |          201927    |

Example-5 | CURDATE() Function

Let’s take a another example of using CURDATE() function. Basically CURDATE() function returns only the date without time. Here it will return the year and week.
