Hi Ani,

Logback does not support cron-like triggering. However, it supports
triggering based on a date pattern, e.g "yyyy-MM-dd"

The schedule "0 0 * * 1 ?" corresponds to first day of the week at
midnight. The pattern "yyyy-ww" corresponds to the same triggering

The link below provides more details:


I hope this helps,
