I've been doing some research around managing our sprint cadence to align teams across time zones and came upon, "N+1" when describing a day of a sprint. I've not been able to find a definition of "N" and how the numbering convention works.
Example: If I wanted our Grooming session to be 2 days before and Sprint Planning to be 1 day before the beginning of a sprint, would I call this "N-2" and "N-1", respectively? And is the first day of the sprint "N0" or would "N0" be the grooming day?
What's a source for this convention (looking for best practice references)? Here's how it was used: Sprint Demo, Retrospective, and Planning sequence with offshore team
