The reporting calendar defines the year on which QuickBooks bases the
report. This can be the calendar year (January through December), your
company's fiscal year, or your company's income tax year.
When you switch to a different calendar, the preset date ranges for the
report change. For example, the fiscal year calendar changes the date ranges as
This Fiscal Quarter
This Fiscal Quarter-to-date
This Fiscal Year
This Fiscal Year-to-date
...and so on.
Switching to the income tax year calendar changes the date ranges as
This Tax Quarter
This Tax Quarter-to-date
This Tax Year
This Tax Year-to-date
