## Challenge #134: US Grand Prix Prelims - Email Dates

Alteryx

I know you guys are as excited as I am for another question from the Grand Prix! This one was also from the prelims for the US Grand Prix. This week, we are focusing on calculating time that has elapsed between emails, but the data need some cleansing first.

Congrats to our Finalists that were announced last week!

Different approach and my datediff was figuring the days on the lesser side so had to convert from hours (datediff of hours) to days in my final formula tool. A lot of tools but this is how I logically think.

Different approach but got there!

While I did get to the solution, I think there is an error. @JimmyG: If you subtract the dates with time included, you get to different numbers. For example, the first one comes to 14 days instead of 15.

@AGoyal - good catch. We actually found this during testing so we added a hint to not worry about the time.
