*Hi there,*

*If the year is 1901, 1902, 1903 do we assume (0) zero for year divided by 4*?

*Many thanks!*

Thank you for your question! The Day Pillar calculation is the most confusing one of the lot 🙂

The short answer: Yes!

The long answer: For those just stopping by, here is the Day Pillar formula (from pages 62 & 66 of the print version):

**DP Formula: DP=R of [(*Yx5)+(*Y/4)+9+*D+BM + I] / 60**

DP = Day Pillar

R = Remainder

*Y = last two digits of the birth year (if born 1900–1999)

*Y = last two digits of the birth year + 100 (if born 2000–present)

**Y = Y – 1 when the person is born in January or February *D = day of birth (for clinical accuracy, I recommend using the “early Zi 子 method”; see Sample Exercise 9)

BM = number of big months passed (see Day Pillar and Gregorian Calendar table)

I = 30 if the month is “even” and I = 0 if the month is “odd” (see Using the Gregorian Calendar in Day Pillar Calculations)

Without having the day or month, I won’t be able to plug in all the numbers needed to get the final answer, but I don’t need that information to address your question. I think it will help to see the numbers plugged in – I’ll randomly use 1902 for the example.

DP = R of [(2X5) + (2/4) + 9 + D + BM + I]/60

So what do we do with the “2/4” part of the equation, the number that is not a whole number? For any number less than one in this equation, use 0.

DP = R of [10 + 0 + 9 + D + BM + I]/60

I hope this helps!

Day pillar i cant get corect answer after divide by 60 most of the time answer is 2 after divide by 60 i calculate in calculator and excel formula as well

Hi again Zalim!

I think I addressed this issue in my answer to your previous post, but it short, you need to find the whole number (integer) remainder for these calculations, not a decimal point. Re-reading the section “Common Questions about Long Division” point 2 (found in Chapter 1, placed after the Year Pillar Calculation Formula) may help clarify further?

Best regards,

Karin
