We need a calendar when we have dates.

If we have more dates we need more calendar (because date of orders is something different from date of invoice for example and must be selected separately)

Calendar is used from min to max but you can decide that date is not important and so you have weeks, month, quarter year.

If you have no date you do not need calendar!

It is not important if date is in fact or not because calendar table is linked to any table where there is a date

Hope it helps

Hi,

1.When we have date fields but not any date dimension then we create the master calendar and use that dimensions.

2.If we do not have continuous date fields in Fact table like there is not regular transaction in the fact table but we need all date fields then we use.

3.We have date field but not in proper order in the format.

4.If you have date field in dimension then connect it with any master calendar then your model looks like snow flake model.

5. Suppose we need future dates in the model.

5. We need fiscal calendar.

And there is many reasons for this
