losing a whole year

i went to cubao earlier today to have my driver's license renewed. i even asked permission from the office secretary that i will be late for work today because of the renewal. when i reached the LTO center in cubao, the guy asked for my license and i gave it to him. i was surprised with what he said. my license isnt due to expire until next year! i checked my license and he was right! what the?

i checked the date in my license the night before (and days before because i was convinced that its supposed to expire this year) and i remember reading that its supposed to expire in 2011. problem is, i forgot its only 2010. ever since 2008-2009, whenever i compute years, for some strange reason, i count 2010 and 2011 as one. not that i see them as one year but its either i forget about 2010 or i forget about 2011. after 2009, i only count one year then i quickly skip to 2012. i think im too eager to be in 2012.
