I've used the Kwiziq library search to try and find a lesson (or any information) on how to use "à partir de", but no luck. For example, can a translation of "from the 24th of July to the 5th of August" be "à partir du 24 juillet au 5 août" as well as "du 24 juillet au 5 août"? What's the rule for using "à partir de"?
And why isn't the rule included in this lesson?
