Yes, Saturday, April 20 will be Weed Day or Pot Smokers Day or just plain 420.
Why, out of all the days of the year, April 20 was awarded this dubious distinction is a bit fuzzy and unclear -- lost, it would seem, in clouds of smoke. Surely this comes as no surprise.
Huffpost keeps a 2009 feature online, "4/20: How 'Weed Day' Got Its Name," that explores the various explanations that have been offered. The relevant Wikipedia entry seems to be pretty much in accord. One can just imagine a bunch of stoners sitting around, passing a joint, and thinking it outrageously funny that, like, if 4:00 is tea time, man, 4:20 should be weed time. The longer Huffpost article mentions, although the Wikipedia article does not, the widely circulated rumor that 4-20 was a police code, at least in California, for pot smoking in progress.
Unless you live in a state that permits medical marijuana use and you have a valid prescription for the herb in that state, we here at The Blog of Days strongly suggest that you not make your celebration of 420 too overt. The Blog of Days does not assist with bail, man.
If you choose not to inhale, Saturday will also be Lima Bean Respect Day and National Pineapple Upside-down Cake Day. We think you should probably choose to celebrate one or the other; we're not sure how these would go together.
Saturday will also be Look Alike Day (find your doppelgänger?), Volunteer Recognition Day, and Record Store Appreciation Day.
Are there still record stores somewhere?
