Do you have a 'mental' calendar? - absolutely!!

Are there dates you alway remember/observe? - I do remember family birthdays and anniversaries.

Do you have problems remembering some dates? - not the ones mentioned above.

Do you keep a paper calendar where you do make notes of dates?
Wall or pocket?
Where does it live?
Where do you get your yearly calendars? - I have a wall calendar in the kitchen. I get the same one every year - a Lake Superior calendar, with pictures of places on the Lake Superior shore line. There are lots of choices as the circumference of the lake is a bit over 1300 miles.

I also have an Old Famer's Almanac Weather calendar in the basket next to my computer.

Do you hang the calendars that you get at your local stores/markets/businesses?
 - no

Funny you asked this today - this afternoon I spent an hour getting my 2010 calendar ready to go - added all the birthdays; made notes of when the cats need Vet appointments, all that sort of stuff.
