Morphology

Julian + calendar

The phrase is a straightforward name + noun composition: 'Julian' (relating to Julius Caesar) + 'calendar' (a system for organizing years), so a learner who knows both words can infer it refers to the calendar introduced by Julius Caesar. This pattern is cross-linguistically common (e.g., calendario juliano, calendrier julien), making the meaning transparent to B1 learners.

Etymology

The Julian calendar is 'named after' the Roman leader Julius Caesar, who in 46 BC made a new calendar with 12 months, 365 days and a leap day every four years to fix the old Roman year. So the name points to Caesar's system and explains why people call the older European calendar the Julian calendar today.
