What does septennial mean?

Septennial refers to a time period or event occurring every seven years.

Why convert septennials to year (leap)?

Converting helps align a fixed seven-year span with leap years for accurate scheduling, legal, or financial calculations that depend on exact day counts.

Is this conversion exact for all date ranges?

No, the conversion is based on an average cycle and may not match every specific date range due to leap year rules and calendar variations.
