The Romans treated leap day as a second sixth day before the Kalends of March, in Latin , This was translated as 'bissextile': the 'bissextile day' is the leap day and a 'bissextile year' is a year which includes a leap day. This second instance of the sixth day of the Kalends of March was inserted in calendars between the 'normal' fifth and sixth days. By a legal fiction the Romans treated both the first "sixth day" and the additional "sixth day" of the Kalends of March as one day. Thus a child born on either of those days in a leap year would have its first birthday on the following sixth day of the Kalends of March. When, many years later, modern consecutive day counts were laid alongside the Roman dates the sixth day of the Kalends of March fell on 24 February. However, in a leap year the sixth day fell on 25 February because the second sixth day came before the sixth day.
