If your date string does not have a year then the date filter will make an educated guess about what the year should be. Sometimes it gets that wrong. See [here](https://discuss.elastic.co/t/grok-timestamp/265236/2) for a longer discussion.

Assuming you are looking in Kibana, expand the date range a year backwards and forwards to see if the events are there.
