17. Can You Use It? Yes!
Here’s a piece of a program:
if (month < 3):
y = float(year) - 1.0
m = float(month) + 12.0
else:
y = float(year)
m = float(month)
a = 0; b = 0
if (y + m / 12 + float(day) / 365 > 1582.87166):
a = int(y / 100)
b = 2 - a + int(float(a / 4))
c = int(365.25 * y - 0.75)
d = int(30.6001 * (m + 1))
jd = float(b + c + d + day + 1720994.5);
18. Can You Use It? Yes!

code is not on your purpose
