Unfortunately, Spotify doesn't provide a direct way to see the creation date of a playlist on the mobile app. However, you can try to infer the creation date by looking at the dates of the first songs you added to the playlist.

To do this, follow these steps:

1. Open the Spotify app on your mobile device.
2. Go to "Your Library" and then select "Playlists".
3. Choose the playlist you are interested in.
4. Scroll down to the first songs you added to the playlist.

The date when these songs were added might give you an idea about when the playlist was created. Please note that this method is not completely accurate and only provides a rough estimate.

For a more accurate date, you might want to check Spotify on a desktop as it sometimes shows more information than the mobile app.
