A calendar with ten regular and one leap month, where each month has exactly five weeks of seven days, has years either 350 or 385 days long. This can only be compatible with leap cycles that have a number of days divisible by five, i.e. not the popular 293 and 400-year cycles (146097 and 107016 days respectively).
