use DAYOFYEAR:

<ul>
<li>the tested Date should lye between Start Date and Finish Date (or on Start or Finish)</li>

When the Finished Date is earlier in the year than the Start Date:

There are almost certainly cleaner ways of doing it, however this should work:

<pre><code>((DAYOFYEAR(finish_date) &gt; DAYOFYEAR(start_date) 
 AND (DAYOFYEAR(@date) &gt;= DAYOFYEAR(start_date) 
 AND DAYOFYEAR(@date) &lt;= DAYOFYEAR(finish_date)))
OR (DAYOFYEAR(finish_date) &lt;= DAYOFYEAR(start_date) 
 AND (DAYOFYEAR(@date) &gt;= DAYOFYEAR(start_date) 
 OR DAYOFYEAR(@date) &lt;= DAYOFYEAR(finish_date))))
</code></pre>

For a start date in Oct 2012 and end date in Nov 2020 this will return all dates in the Oct-Nov range. If in fact would want it to return all Dates when the range is greater than a year (and hence covers all dates of the year) you could add:

<pre><code>OR DATEDIFF(Day, start_date, finish_date) &gt; 356 
</code></pre>

before the final bracket.

<pre><code>SELECT * FROM tableWithDates t WHERE month(t.start) &gt;= 11 AND month(t.finish) &lt; 3 
</code></pre>

if you want the first of march it will go like this:

<pre><code>SELECT * FROM tableWithDates t WHERE month(t.start) &gt;= 11 AND (month(t.finish) &lt; 3 OR month(finish) &lt;= 3 AND day(finish)&lt;=1)
</code></pre>

Depending on the size of the data you will run this at. You can get into performance problems, as MySQL can't use indexes of calculated columns.
If you run into this i suggest spitting the month AND/OR day into separate columns.

Edit:
Given an one parameter input as '2008-02-29'

<pre><code>SELECT * FROM tableWithDates t 
WHERE 
 month(t.start) &gt;= month('2008-02-29') AND day(t.start) &gt;= day('2008-02-29')
AND month(t.finish) &lt;= month('2008-02-29') AND day(t.finish) &lt;= day('2008-02-29')
</code></pre>

You can use some date extract function and then check your condition..

for example.

<pre><code>SELECT EXTRACT(MONTH FROM TIMESTAMP '2013-11-01 20:38:40');
 this will give ouput start month as 11

SELECT EXTRACT(MONTH FROM TIMESTAMP '2014-03-01 20:38:40');
 this will give ouput end month as 3
</code></pre>

now you can check the condition from above two result..

I'm wondering what would be the easiest way in MySQL to check if given date is in range regardless of the year.

In database table I have two <code>DATE</code> fields: <code>start</code> and <code>finish</code> stored in <code>YYYY-mm-dd</code> 

if <code>start = 2013-11-01</code> and <code>finish = 2014-03-01</code> anything between 1st of November and 1st of March of any year should be accepted.

Valid dates:
<code>2020-01-01</code> <code>1980-02-28</code> 

Invalid dates:
<code>2013-10-30</code> <code>1968-07-30</code>

我想知道在MySQL中检查给定日期的最简单方法是什么，而不管年份如何。在数据库表中，我有两个DATE字段：start和finish存储在YYYY-mm-dd中如果start = 2013-11-01和finish = 2014-03-01在任何一年的11月1日到3月1日之间有任何变化的话，都应该被接受。有效日期：202...
