Why does the conversion use leap years instead of regular years?

Leap years include an extra day to keep calendars aligned with Earth's orbit, making this conversion more precise for calendar-based calculations.

Is this conversion accurate for all calendar systems?

No, it applies specifically to the Gregorian calendar and may not be suitable for other calendar systems with different leap year rules.

Can this tool be used for financial and legal date calculations?

Yes, it is helpful for calculating exact day totals in contracts, payroll, and interest where leap days must be included.
