To the best of my knowledge, this is not a national holiday. There are no particular religious affiliations involved. No greeting cards, no candy, no fireworks, no special furniture and mattress sales. You don't even have to take off work, though it might help if you want the full experience of, yes, Sacramento Beer Week, which is this coming week.
The week of festivities features a slew of events, including Draught Beer Seminar & Luncheon at Lounge on 20, a California Beer Dinner at Mulvaney's, a Cider Pairing at Magpie and Tacos and Beer at Rubicon.
There are also plenty of Pint Nights and beers specials to commemorate Beer Week. There's so much going on that you really need to check the Web site for all the details.
