Well technically, wouldn't the 20th be the last full day? The moment the clock hits 12:00 and it's the 21st, everything goes boom.
Actually I believe there is an hour/minute that it will end on the 21st, not 12:00.01.
hey, sushi is good! play nice... LOL!
No biggie, we have two oceans to still pick from on either side of our continent......
