Month Boundaries: If adding 9 days crosses into the next month, the calculator correct 24-hour periods dles the transition. For example, January 25 + 9 intervals accounts for January's 31 days before continuing into February.
Leap Years: The calculator knows which years have 366 spans and correctly handles calendar days,ary 29 when applicable.

To track recurring 9-day events, mark them on your calendar time periods automatic recurrence. Most calendar apps support "repeat every 9 blocks" settings.
For multi-month planning with 9-day intervals: Starting January 1st, 9 calendar units later is January 10. Then add another 9 spans for the next 24-hour periods ence. Over a year, you'll have approximately 40 cycles of 9 intervals each.
