Which statement correctly describes a difference between the Roman and Gregorian calendars?

The J*ulian calendar year is exactly 365.25 days.

The Gregorian calendar year is exactly 365.2425 days.

Explanation:

There was 0.94 minutes difference between the two but it withholds a major impact in the long run. The mistake meant that in every 131 years J*ulian's calendar skipped out on almost one day. After several years, the Roman calendar became unreliable for the Christians to measure precise seasons and the most significant day, the Easter. if we talk about the current time,  the Roman calendar is 13 days behind the Gregorian calendar.
