The calculator uses the conversion formula:
Where:
Explanation: The calculation uses the average month length accounting for leap years over a 4-year cycle.
Details: Converting between time units is essential for project planning, financial calculations, scientific research, and comparing durations across different measurement systems.
Tips: Enter the number of days (must be positive). The result will show the equivalent duration in months based on the average month length.
Q1: Why 30.4375 days per month?
A: This accounts for the average month length including leap years (365.25 days/year ÷ 12 months/year = 30.4375 days/month).

A: It provides a good average but actual months vary from 28-31 days. For precise calculations, consider exact calendar dates.
Q3: When would I need this conversion?
A: Useful for financial calculations (interest accrual), project timelines, scientific experiments, or when comparing durations.
Q4: Can I convert months back to days?
A: Yes, multiply months by 30.4375 to get approximate days. For exact conversion, use calendar functions.
Q5: What about business months (30 days)?
A: Some industries use 30-day months. For this, simply divide days by 30 instead of 30.4375.
