Morphology
The meaning is directly compositional: 'old' (former) + 'style' (manner/type) + 'calendar' yields 'a calendar of an earlier/old style'. A B1 learner who knows the constituent words will understand it refers to an older or previously used calendrical system (even if they may not know the historical label 'Julian calendar').
Etymology
Old Style calendar comes from the time when countries changed from an older calendar to a newer one. When people kept dates from the earlier system they called them 'Old Style', so today the phrase means a date written in the older calendar.
