Specific Date: A "Universal Reset"

Everyone expires on the same calendar day, regardless of when they finished the work.

• Best for: Annual compliance, company-wide deadlines, or fiscal year requirements.

• Scenario: If the date is set to Dec 31, it doesn't matter if someone finished in January or November—they both reset on Dec 31.

Interval: A "Personal Clock"

The expiration is triggered by the individual's completion date.

• Best for: Certifications (like forklift or CPR) that are valid for a specific duration (e.g., exactly 2 years).

• Scenario: If the interval is 1 year, a person who finishes in May resets next May; a person who finishes in August resets next August.
