In this SQL Server tutorial, I will share my experience and the possible reasons behind the error “the conversion of a date data type to a DateTime data type resulted in an out-of-range value SQL“.
Recently, I was working with date and time data types in SQL Server. I was trying to check what date and time values are valid in SQL Server when I faced the error “the conversion of a date data type to a DateTime data type resulted in an out-of-range value SQL“.
The SQL query that I executed was:
SELECT CAST('02/29/2021' AS DATETIME) AS Date

Solution: The conversion of a date data type to a datetime data type resulted in an out-of-range value sql
We face this error if we supply a date value that is not valid. For example, If I enter the date 2021-12-32 i.e. 32 cannot be a day of any month, I will get the same error.
In my case, I entered the day value as 29 for the February month of a non-leap year. Then I entered a valid date i.e. 29 February and I got the expected result. The query became:
SELECT CAST('02/28/2021' AS DATETIME) AS [United States Date]

The following are common mistakes that we make while entering a valid date:
- If you specify any year before than 1753, you will face this error.
- Entering the day as 29 Februrary when the year is not a leap year.
- Entering the day as 31 April i.e. the April month has only 30 days.
- Entering the month value greater than 12 i.e. there are only 12 months in a year.
Therefore, while trying to specify a date value in SQL Server, keep in mind to specify the valid date and not to make the above mistakes.
