Count or Sum Number of Entries per Year

Hi,

I have a large log between 2012 & 2013 & soon into 2014.

I attempted to use the following functions, but neither is giving desires results. Do these functions not read dates?


=COUNT($C$16:$C$10000,"*2013*")

=COUNTIFS($C$16:$C$10000,"*2013*")


=SUMIF($C$16:$C$10000,"*2012*",$C$16:$C$10000)

Please advise & even better provide a function.

Thanks
