time series modeling - formatting for quarterly dates?

[jacob_a]

For time series modeling, how do I format quarterly dates? THANKS

It’s best to use standard dates and format like: “2018-01-01”, “2018-04-01”, “2018-07-01”, “2018-10-01” for quarterly data. We will detect this as quarterly time steps.
