We skipped 10 days in 1582 due to the implementation of the Gregorian calendar by Pope Gregory XIII. This change was made to correct a drift in the Julian calendar, which miscalculated the solar year's length by 11 minutes annually. As a result, October 4, 1582, was followed by October 15, 1582. This adjustment helped realign the calendar with the equinoxes and seasons, ensuring more accurate date-keeping and eventually becoming the widely adopted system.
