# Note
- In the "Differences" module, if the begin time is greater than end time, the results will display as negative numbers as below:
- Algorithm For [Years] And [Months]
[Years] = [Seconds] / 3600 / 24 / 365.25
In above expression, 365.25 = the average days in 4 years (3 non-leap years + a leap year) = (365 * 3 + 366) / 4.
[Months] = [Seconds] / 3600 / 24 / 30.4375
In above expression, 30.4375 = the average days in 48 months (the months of (3 non-leap years + a leap year)) = (365 * 3 + 366) / 48.
