Get year, month or day from numpy datetime64

Question

I have an array of datetime64 type:

dates = np.datetime64([\'2010-10-17\', \'2011-05-13\', \"2012-01-15\"])

Is there a better way than loop

Answer 1

Anon's answer works great for me, but I just need to modify the statement for days

from:

days = dates - dates.astype('datetime64[M]') + 1

to:

days = dates.astype('datetime64[D]') - dates.astype('datetime64[M]') + 1
