Common questions about 9 months ago

Can calculating a past date several months ago cross a leap year, and what impact does that have? ▾
Yes, subtracting several months can cross a leap year, potentially adding an extra day to the time span, which may affect calculations involving exact day counts.
Why is subtracting a medium number of months useful for financial or project planning? ▾
Subtracting several months helps assess meaningful periods in the past for trends or milestones, aligning with reporting cycles and providing context for medium-term planning.
