How old does code need to be before it's considered legacy?

How do you define legacy code?
|
||
|
|
|
||
|
|
Code that was written by someone else?
|
||
|
|
|
||
|
|
Code that doesn't have tests?
|
||
|
|
|
||
|
|
Any code that has been released to production?
|
||
|
|
|
||
|
|
Code that's more than a day old?
|
||
|
|
|
||
|
|
In a talk I recently watched, the speaker suggested that any code written more than thirty minutes ago is legacy code.
|
||
|
|
|

|
|
Once you've written some code and left it for half an hour, you need to re-read it to remember and re-learn what the code does and decide how you want to implement your next requirement.
|
||
|
|
|
||
|
|
This is the same approach for code that was written longer ago or written by someone else.
