Does Interphase have stages? Because... a certain search site says "3 stages" or "4 stages" but then my textbook says "critical events"

I need desperate help.

No, interphase does not have stages.

Explanation:

The cell cycle has 3 phases: Interphase, Mitosis, and Cytokinesis. Interphase is the longest phase. During that stage, the cell grows to its full size and duplicates its DNA. These steps are not counted as stages.

Sorry if this is wrong, this is just what my teach taught me.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
