<br>
Why did you change the recommended 92 days into 91?<br>
<br>
Consider June, July and August:<br>
<br>
June has 30 days<br>
July has 31 days<br>
August has 31 days<br>
<br>
So, on September 1st, June 1st is 92 days ago, and you can delete the logs for <br>
May 31st, which are older than 92 days.<br>
<br>
If you deleted older than 91 days, you would be deleting June 1st on September <br>
1st, and one day this might be significant to someone.<br>
