Adobe Photoshop free trial version period - 7 days or 30 days ?

Is free trial version of Adobe Photoshop available for 7 days or 30 days ? Is there a registration required for Photoshop trial version ?

Hi,

In case of Adobe Photoshop, there are Creative Cloud and Creative Suite plans available. For each of them, trial version period is different:
Adobe Photoshop CC - the trial version period is 7 days
Adobe Photoshop CS6 - the trial version period is 30 days
