Q: creating a new event in photo: impossible? grrr

The new Photos application does not have the concept of "events" whether old or new. It has albums, and your iPhoto events would have been converted to albums when your pictures were migrated from iPhoto to Photos. You certainly may create your own new albums and add pictures to them.

Moments in Photos are the new Events, i.e. groupings of photos sorted by date taken.

When the iPhoto Library was first migrated to Photos there was a folder created in the sidebar titled iPhoto Events and all migrated iPhoto Events (which are now Moments) are represented by an album in that folder. To open the sidebar if it's not already open use the Option+Command+S key combination.

There's a way to simulate events in Photos.

When new photos are imported into the Photos library go to the Last Import smart album, select all the photos and use the File ➙ New Album menu option or use the key combination Command+N.  Name it as desired.  It will appear just above the iPhoto Events folder where you can drag it into the iPhoto Events folder

 

When you click on the iPhoto Events folder you'll get a simulated iPhoto Events window.

The downside to the simulation is that the Albums/Events can only be sorted automatically by Title. But they can also be sorted manually, either in the sidebar or in the folder's window at the right.

Ask Apple for more sorting options in Photos via https://www.apple.com/feedback/photos.html.

It is impossible since Photos does not have Events - it has Moments and collections that are automatic as of now

Tell Apple what you want

All my iPhoto events appear as someone below discribed. My problem is that all events and also the uppermost 'Pictures' are sorted with the oldest pix at the top! How do I change that such that the newest pix are the easiest to reach?

Also - under 'Albums' there is a folder called 'All Pictures', but they seem to be in no specific order at all, a total mess. I've noticed this on my iPad and iPhone earlier, but didn't care to dwell on it. But now, if I'm going to switch from iPhoto to Photos, I need to know how to sort the pix.

Sorry, point taken. I was going to post a separate thread, as I hadn't found any good answers anywhere. But I'll look more closely before posting a question.
