[Solved] Weekly indexes instead of daily

Right now I am working with indexes that are created daily using the following output in my config file: output { elasticsearch { hosts => ["localhost:9200"] index => "logstash-events-%{+YYYY.MM.dd}" } } This is fine, but I was wondering if it is possible to have it make new indexes every week.
