How this calculator works

Next audit date = last audit date + interval months. Reminder date = next audit date - lead days.
Next audit date = last audit date + interval months. Reminder date subtracts reminder lead days. Latest internal date adds grace days.

Inputs explained

Start date

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

Counting rule

Use the rule from the contract, court rule, statute, plan document, agency notice, or policy.

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

This is a planning estimate only. It does not decide rights, obligations, eligibility, jurisdiction, tolling, service rules, holidays, court closures, or legal compliance.

Example scenarios

Planning example

A quarterly audit interval from January 15 creates the next due date three months later, with a reminder before that date.
