Persistent Notification for Calendar Events The Google Calendar app recently updated to the new Material Design look. I've noticed that notifications have changed in a way that I do not like. 

When a calendar event comes due, it appears as a notification in the Notifications bar at the top of the screen. In the past, it stayed there for about 48 or 72 hours (not sure exactly, but it was well over 24 hours) as long as I did not mess with it. But now, it seems to only stick around for a very short amount of time (as long as the event is ongoing, I think). In other words, it seems that once an event is over, the notification disappears. 

This is not good news for me, I used calendar events as reminders to get things done. (Ex: "take out the trash" on Wed night... I would always see this in the evening, and can put it off until later in the evening if need be. Worst case: when I go to bed, I would see the notification still sticking around, and then go put the trash out.)

I'm looking for a way to get the previous functionality. Is there a trick for this? I'm also open to trying free calendar or task apps that do this.

Suggestions, please?

I am replying (I see no one else has) because I have always used the calendar/notifications functionality in the EXACT same way you have, and was also distressed of this change in functionality.  I think we are in the minority, though, because your post is the first acknowledgement I have even seen anywhere about this issue.

The only solution I have is to look at third-party apps.  Although someone appears to have ported an older ICS/Jelly Bean-era version of the stock calendar which you can find in the Play Store, I have not used that too much.  At the moment I am using Business Calendar, which I THINK comes somewhat close to replicating the functionality you and I are accustomed to (although I am still watching it to see).  I also gave Today Calendar a very close look -- it is much closer to the Google aesthetic, and even has aspects of Material Design implemented.  It appeared also to have persistent notification functionality, although for some reason I had problems with the syncing.  This may have been fixed.

If you have come up with any solutions, I would love to hear them!  Good luck!
