Planck time is a fundamental time scale derived from universal constants, representing an extremely small interval relevant in quantum gravity and early universe physics.

Why use Julian years instead of calendar years?

Julian years are fixed units used in astronomy based on exactly 365.25 days, providing consistent, standardized durations for long-term calculations.

Can I use this converter for everyday time conversions?

No, this converter is designed for converting theoretical quantum time intervals into astronomical-scale years, and is not suitable for common timekeeping.
