This calculator counts actual days based on the dates you submit; a year is 365 days and a leap year is 366 days. It determines the difference between 2 dates, for example, 2/5/2016 minus 2/1/2016 = 4 days. In other words, properly stated, on 2/1/2016 it is 4 days until 2/5/2016, and on 2/5/2016, 2/1/2016 was 4 days ago.
