How this calculator works
This shortcut subtracts 11 calendar months from your reference date using calendar-month rules, not a fixed day estimate.
Month-end references adjust when the target month has fewer days than the starting month.

From July 23, 2026, 11 months ago was August 23, 2025.
Use fiscal period closes or statement dates as the reference when auditing multi-month windows.
Practical use cases

Browse related month shortcuts or switch to day-based lookbacks when your policy counts fixed day totals.
