Our DataPoint add-on for PowerPoint, or our easier Dynamic TIME add-on, can do that for you. Both add-ons will allow you to countdown to a given date. If you only have to display a countdown clock, and nothing more, then use our Dynamic TIME add-on. On the other hand, if you want to display more dynamic information like news, weather, announcements, promotions, etc from various data sources, then use DataPoint. In this article, we will use DataPoint, since Dynamic TIME is so easy to use, even without instructions.
Open the Access database and open the only table in there, called TableTargetDate. Open the table by double clicking its name. This opens a new window with the current table content or row information. At the column named Target, enter the date for Christmas, 12/25/2017, and close the table window again. This will save the value to the database file.
The calculation is performed only once here, at the time of opening, and it will not refresh its calculation automatically. DataPoint will take care of the continuous updating.
Make sure to set the refresh rate to every second, in case you want to display the number of seconds. Here is a great article on how to link a Microsoft Access database in PowerPoint.
Link every text box on its corresponding column of the query (days, hours, minutes and seconds). Once all your text boxes were linked on the query, then you can run the slide show and the countdown to Christmas will start automatically.
