Cohort time

To visualize cohorts even better, we need to learn how to deal with time in cohorts.

There is a time of cohort creation, during which we select objects in the cohort, for example, the month when clients made the first payment.

There is a time of cohort life, this is the time from the moment of cohort formation to the date of the last activation of any object in the cohort. 

Cohort analysis time is the time for which we study the accumulated properties of objects in the cohort.
