Date Calculation Logic

No Repeat

Directly calculates the difference between target date and today.

Monthly Repeat

Starting from the target date, increments by repeatInterval months to find the first date >= today.

Yearly Repeat

Starting from the target date, increments by repeatInterval years to find the first date >= today.

Sort Order

1. Today (days === 0) first
2. Future dates ascending by days
3. Past dates last
