Explanation | The Month Fortune Formula for people born in B.C. is `G2=3+m+12(1-y) (Mod 10) & C2=m (Mod 12)'. The Month Fortune Formula for people born in A.D. is `G2=3+m+12y (Mod 10) & C2=m (Mod 12)'. If `y' is the year and `m' is the month of a person born in Gregorian calendar, the `Month Fortune Co-ordinates' calculated are called the `Origin of Month Fortune Co-ordinates', (UN2,ZN2). The origin of `Month Fortune Co-ordinates' is the starting point of one's `Month Fortune Co-ordinates'. The `Month Fortune' of a person follows the order of `Fortune Co-ordinates' and it moves to the next pair of co-ordinates in next month. The `Month Fortune' is revolving around in one direction only. It always revolves clockwisely and repeats in 60 `Fortune Co-ordinates' (G2,C2), where `G2' and `C2' are integers. When the `Month Fortune' of a person starts to move from the origin of `Month Fortune Co-ordinates' (UN2,ZN2) and it comes across `Joint of Month' of two consecutive months, it shifts to the next `Month Fortune Co-ordinates'. `G2=(Mod 10)' is a special modulated function such that the smallest value of it is 1 and the largest value of it is 10. If G2>10 then `G2' becomes `G2-10' and if G2<1 then `G2' becomes `G2+10'. Thus, the value range of `G2=(Mod 10)' is from 1 to 10. `C2=(Mod 12)' is a modulated function such that if C2>11 then `C2' becomes `C2-12' and if C2<0 then `C2' becomes `C2+12'. Thus, the value range of `C2=(Mod 12)' is from 0 to 11. If `y' is the year and `m' is the month of a person's fortune in Gregorian calendar, the result calculated by the formula is called the `Month Fortune Co-ordinates' of the person. The `Month Fortune Co-ordinates' are expressed as (G2,C2), where the value of `C2' is approximately equal to the solar month, `m', but the beginning of a new month is not the first day of the month. The critical value between two consecutive months is called `Joint of Month'. `Joint of Month' is the boundary of two consecutive months. It always lies on from the 3rd to 8th day of a solar month. In general, not for precise calculations, `Joint of Month' can be regarded as the 6th day of a month. If the date is within the 3rd to 8th day of a solar month, precise calculations should be carried out. That is, if the time of a date is after `Joint of Month', the month is `m'. If the time of a date is before `Joint of Month', the month is `m-1 (Mod 12)'. The time and date of `Joint of Month' between two consecutive solar months always change from month to month. `Joint of Month' also varies according to the longitude and latitude of a place. The exact date and time of a `Joint of Month' can be found in a Chinese calendar. |
Example | Assume to find the month code of 15th Jan., A.D.1994. Since the date is after `Joint of January' on 5th Jan., A.D.1994, the month is January. m=1 and y=1994. Apply the `Month Fortune' Formula. G2=3+m+12y (Mod 10) & C2=m (Mod 12). G2=3+1+12x1994 (Mod 10). G2=23932 (Mod 10). G2=23932-2393x10. G2=2. C2=m (Mod 12). C2=1 (Mod 12). C2=1. Hence, the `Month Fortune Co-ordinates' (G2,C2) are (2,1). The `Month Code' is `02', `B1', `2B', `BB' or `EUT-CHO'. |
