What does septennial refer to?

Septennial refers to a period lasting seven years or something that occurs every seven years.

What is a sidereal hour?

A sidereal hour is one twenty-fourth of a sidereal day, representing Earth's rotation relative to distant stars, used mainly in astronomy.

Why convert septennials to sidereal hours?

This conversion helps link extended human time periods with astronomical time measurements for planning and analysis.
