Comprehensive and Detailed Explanation From Exact Extract:

Tableau allows fiscal calendars to be defined at the data source level, affecting how all date fields behave across the workbook.

According to Tableau documentation:

Fiscal calendars must be set using Data Source Date Properties.

Once set, this becomes a default property for all date fields unless overridden.

This allows charts, hierarchies, and date parts to automatically follow the fiscal year starting in February.

Correct procedure:

Go to Data Source.

Open Date Properties.

Set Fiscal Year Start = February.

(Optional) Adjust Date Field Default Properties.

This ensures all charts and date hierarchies use the fiscal calendar automatically.

Why the other options are incorrect:

A . Right-click on axis Use Fiscal Calendar

This option does not exist in Tableau.

B . Set Fiscal Year in Data Preview

Not supported; fiscal configuration isn't made in the preview window.

C . Use FISCALYEAR() / FISCALQUARTER()

This is manual, requires custom fields, and does not configure Tableau's built-in fiscal calendar system.

This is more work and not the correct method.

Only Option D configures the fiscal calendar globally and correctly.
