Continue by adding to the new total the number of days in the first seven months of 2009 that have already passed which are 31 + 28 + 31 + 30 + 31 + 30 + 31 = 212 days and the 13 days of August to get "Base" = 732920 + 502 - 20 + 5 + 212 + 13 = 733632. What this means is that it has been 733632 days since the base date. Substitute the value of "Base" into the above equation (i) to get 733632 = 7
