How durations are converted
We use the second as the reference. Each value is converted to seconds and from there we derive the rest by dividing by the corresponding number of seconds.
How is a year calculated?
We use a fixed 365-day year for simplicity. For leap years or calendar-aware calculations, use a date-aware tool instead.
