Frequently Asked Questions
How does the months ago calculator work?
Our calculator moves backwards through the calendar month by month, accounting for varying month lengths and year transitions. It handles all the complexities of different month durations and leap years to provide accurate past dates.
What's the difference between 3 months ago and 90 days ago?
The difference can be significant. Three months ago (September 12, 2025) accounts for actual calendar months, while 90 days ago (September 13, 2025) is an exact count of days. The variation occurs because months have different lengths (28-31 days), making the "months ago" calculation more natural for month-based analysis like financial reports and academic terms.
How are months calculated across year boundaries?
When calculating months across year boundaries, our calculator:
- Maintains the same day of the month when possible
- Adjusts for months with fewer days (like February)
- Handles leap years automatically
- Considers year transitions seamlessly
For example, going back 2 months from March 31 will land on January 31, not January 30.
How does the calculator handle February and leap years?
The calculator handles February and leap years with special logic:
- Recognizes when February has 28 or 29 days
- Adjusts end-of-month dates appropriately
- Maintains consistent month-end calculations
- Ensures accurate date handling across leap year boundaries
What's the maximum time range for calculations?
Our calculator can handle calculations up to 120 months (10 years) in the past
