A Psalm a Day: DOY = d + 30m + g
A Psalm a Day: DOY = d + 30m + g I enjoy beginning my days by singing through a Psalm, one each day, in order from Psalm 1 to Psalm 150. With 365 days in a year (usually) I will have sung through the entire Book of Psalms twice, with third time through the first 65 Psalms! (On Day 119 I must take some creative license and break the 22 sections into thirds!) I’m not used to keeping track of each day of the year. There are computer applications and internet sites that can do that for me, but I prefer to do it the old-fashioned way: mathematics. Here’s my formula: DOY (Day Of Year) = d + 30m + g Where, d = day of the month 30m = number of completed months, multiplied by 30 g = net days gained This formula takes into account the fluctuation from month to month of 30 days or 31 days, and the four-year variance in February from 28 to 29 days. For example: Today’s day of the month, plus (30 x completed months) plus gain = equals the day of the year. December 9 = 9 + 330
