Hi
Is there an easy way to get start and end dates that are consecutive and show them as one result. So instead of...
1 July 2019 Holiday
2 July 2019 Holiday
3 July 2019 Holiday
4 July 2019 Holiday
5 July 2019 Business
6 July 2019 Business
...this:
1-4 July 2019 Holiday
5-6 July 2019 Business
I'm sure there's a terminology for this but can't think of it. Clues would be preferable than an actual answer.
Thanks!

Subtract a ROW_NUMBER() from the date to get the group for consecutive dates. I'll let you work out the details of the ROW_NUMBER() since you said you preferred clues to actual answers.

PIVOT is too restrictive for what the OP is trying to accomplish, because it only allows one aggregate function, and you need a MIN() and a MAX().
