16. Timekeeping and Calendars
The Julian calendar, introduced by Rome, standardized the year and profoundly influenced how Western societies track time. Meanwhile, the Persian solar calendar offered remarkable accuracy, guiding agricultural and religious observances for centuries. These systems not only organized daily life in their own eras but also shaped the global calendars in use today. The legacy of their innovations endures in our holidays, schedules, and annual cycles (Time and Date).
