How many months is 90 days?
90 days is approximately 3 months because there are approximately 30 days in a month. However, it should be noted that some months have 31 days, and February has 28 days (or 29 in a leap year), so it's not an exact conversion.
We can also calculate this by dividing 90 by the average number of days in a month which is 30.4. So, 90/30.4 = 2.96 which is almost 3 months.
