Common mistakes
- Dividing by 30 instead of 30.44. Months vary from 28 to 31 days, so the 30.44 average tracks a full year more accurately than a flat 30.
- Treating the decimal months value as months and days directly. 1.48 months is not 1 month 48 days, it is 1 month 14.56 days.
- Using this average for a specific date span. Calendar months have different lengths, so use a date calculator when you need actual start and end dates.
