a03.03.2018
b17.01.201824.02.2018
b22.08.2018

and I need for my model output like this:

userdate_fromdate_tomonthdays
a13.02.201822.02.201802.201810
a03.03.201831.03.201803.201819
a01.04.201830.04.201804.201830
....
a01.09.201830.09.201809.201830
b17.01.201831.01.201801.201815
b01.02.201824.02.201802.201824
