An infographic explaining the reason for leap years: ''Since our calendar has exactly 365 days in a year, we could lose almost six hours from our calendar every year if we did not add February 29 to every fourth year.'' A graph depicts the growing number of lost days each year without a leap year: ''24: The number of days that our calendar would be off after only 100 years without leap days!'' A graphic shows the traditional roman calendar with 10 months: ''Our calendar is based on the early Roman calendar used by Romulus, which had only 10 months beginning in March.''
