Problems with date before 1913.12.13

[gerok]

Good Morning !!

The calendar plugin works perfectly (Thanks!!) but…

On some servers works fine but in other dates before 1913.12.13 appear on January 1 always.

Do you know any why? I think it's a matter of mysql.

Thank you very much anyway

Sorry, the date is 1901.12.13, not 1913.12.13.

Thanks
