macro to return max value in a time-series

Hello,

I am very new to this please excuse my ignorance. I have daily rainfall time-series and my objective is to find annual maximum daily rainfall. My data range from 1941 till 2004 so you can imagine why it is irksome to do it manually. Is there a macro that can extract the annual maximum value from each year taking into consideration that not every year has 365 days. I attach a sample.

Regards

Mohammed
