Many internet users have questioned the logic behind this. One user asked, “What happened in the second week of October in 1582 that it was so eagerly removed from the calendar to erase it from history?”

Another user wrote, “10 days were removed in October 1582 to more accurately align the calendar with the solar year.” A third user commented on Instagram, “The calendar is messed up.”

Clearing the air four years ago, American astronomer and science communicator Neil deGrasse Tyson tweeted, “By 1582, the Julian calendar had accumulated ten extra days relative to Earth’s orbit, with a leap day every four years. So Pope Gregory dropped the 10 days that year and introduced a new, more accurate calendar, with October 4 being followed directly by October 15.”
