Changing the date of your photos

Press and hold the [Ctrl] key and press the [A] key to select the folder that contains the photos to have the date changed.

Click [Edit] > [Change Date of Selected Media Files ...].

Select how to change the date.

Change dates of all media files to keep their time the same, relative to the selected media file: If you know the actual shooting date and time of the photo, you can change the date which is based on the selected photo.
Change date by specifying a time interval: If you want to adjust time difference such as for photos taken during overseas travel, set the time forward * hours or set the time back * hours.

Click [OK] and the date and time will be changed.

Right-click the photo you want to change the date for, then click [Properties].

Click the date or time of [Date taken] and enter a number, then press the [Enter] key. Date will be changed.
