The photo app on the iPad gives the option of showing photos by years, months, days or all photos. To organise photos it is easy to create albums and move photos into them. On the photos screen tap on ‘select’ and then tap on each photo to be moved to an album and a blue tick will appear in the corner.
Now tap on the 3 dots and select ‘add to album’. Now you will be given a screen where you can either create a new album or move the selected photos to an existing album.
At the bottom of the screen as well as photos/library (depending on your iPad model) there is the option to display albums or search for photos.
