"Do not display information that is redundant or that can be inferred by the user: if the date range ends in less than a year from when it begins, do not display the ending year. If the range ends in the same month that it begins, do not display the ending year or month.",

"Additionally, if the date range begins in the current year and ends within one year, the year should not be displayed at the beginning of the friendly range.",
