How to calculate the stem & branch of the Hour
- Take the daily stem and lookup the stem and branch of the first double hour
- If daily stem is S1 or S6; 1st double hourly stem = 1
If daily stem is S2 or S7; 1st double hourly stem = 3
If daily stem is S3 or S8; 1st double hourly stem = 5
If daily stem is S4 or S9; 1st double hourly stem = 7
If daily stem is S5 or S10; 1st double hourly stem = 9
- Double hourly stem = Add number of double hours to the 1st double hourly stem. (after S10 the stem cycle starts again with S1…)
- Double hourly branch = Add number of double hours to 1 (the 1st double hourly branch, 23:00-01:00) (after B12 the stem cycle starts again with B1…)
