How this calculator works

The calculator counts the entered appeal window from the denial notice date using the selected method.
Estimated Appeal Deadline = start date plus or minus the entered day count, using the selected calendar-day or business-day method and optional weekend adjustment.

Inputs explained

Start date

The date the clock starts, such as notice, purchase, discovery, denial, renewal, or filing period date.

Weekend or closure adjustment

Some rules move dates that land on weekends or closures, while others do not. Choose the rule you need verified.

Understanding your results
