# Time Structures

A few categorizations of time structures are as follows:

* **Sequential vs. Cyclic** Sequential: Jan 1, ...., Dec 31 Cyclic: days of the week, months of a year
* **Hierarchical/Multiple Resolutions**   Ex. years $$\rightarrow$$ months $$\rightarrow$$ weeks $$\rightarrow$$ days and so on This allows us to aggregate/disaggregate time at different resolutions It also allows us to visualize different levels of detail
