A teacher was lamenting to me that, unlike PowerPoint, Google Slides will not allow you to add a date to the slides. This does not do it automatically when you open the Slides, but I created a Free Add-on that will allow you to add and update a date on the Google Slides.
Install Add-on
Collects NO User Data
This Add-on collects NO user data.
Use the Add-on Menu
After installing, use the “Add-ons” menu in Google Slides to select the “Add a Date” Add-on.
Select “Add Date”
Choosing the “Add Date” option in the menu will add a textbox to the FIRST SLIDE with the current date. You can use this to remind yourself, a collaborator, or a student the last time the information was updated. If you’re a teacher, to allow viewers to know what date the information was taught/presented.
Update the Date
You would not want to edit the date manually! If you want to update the date and time use the Add-on menu and select “Add a Date” and “Add Date.” The textbox that was created by the Add-on is deleted and a new textbox is placed in the upper right with the current date and time.
Domain Install
This Add-on uses NO user data. Suggest to the Google Workspace Admin that they can domain install this for all users!
