What is a Julian year?

A Julian year is a defined time period of exactly 365.25 days or 31,557,600 seconds, used especially in astronomy for consistent long-term measurements.

Why convert Julian years to hours?

Converting Julian years to hours helps represent long astronomical timescales in smaller, more practical units suited for scheduling and analysis.

Is the Julian year the same as a calendar year?

No, the Julian year is a standardized fixed duration and does not match calendar years like the Gregorian, which account for leap years and other adjustments.
