I manage fine at the moment with folders names in the following way, YYMMDD but I'm looking at lightroom.
By using 140830 for today's pictures, it's easier to sort them than using the month in the folder name, because April will list before January.
I presume you are therefore too young to have photos taken before 01/01/2000? I use YYYY_MMDDxxxx, where xxxx is a serial for that day for "hobby" photos. I have separate databases where I log sightings / photos / flights etc have the details of photos from which I will inserting links following a forthcoming software upgrade (HandBase).
