History of Calendar in Timeline
Calendars are systems for organizing days by naming time periods like days, weeks, months, and years. A date specifies a single day within this system. Calendars can be physical records (like wall or desk calendars) or lists of planned events (like court calendars), and can sometimes be chronological lists of documents.
