Does Julia have a Pkg or methods that can process temporal data and extract relevant features?
thanks!!!

What is a relevant feature very much depends on the task at hand. What problems are you trying to solve?

That is still a very vague description, but you may have a look at the following packages.

As Fredrik says it’s hard to say what sort of functionality you really need, but what you describe above (going from hourly do daily frequency) is very basic, so you might want to look at the `TimeSeries` package, particularly this part of the documentation:
