From The Washington Post: anti-tax demonstrations are complicated by the tax day move. “Tax Day this year falls on Monday, April 18. But most anti-tax events — in the District and around the country — are still slated for the traditional date of April 15… ‘The 18th is wrong,’ said Grover Norquist, the president of Americans for Tax Reform. ‘It’s like moving Christmas or something.’… Every year on April 16, the District celebrates Emancipation Day to mark the date in 1862 when slaves in the city were freed. But because April 16 is a Saturday this year, the holiday will be observed on April 15. So Tax Day was moved back to Monday, because the IRS observes D.C. holidays as it does federal holidays… Congress — the primary audience for anti-tax demonstrations — does not follow the same calendar as the IRS, and the House and Senate are scheduled to be in session April 15 but out of session the week of April 18…Norquist’s group is planning to have its big Capitol Hill news conference on Thursday, April 14, because that’s when it will be easiest to ensure that sympathetic lawmakers show up.”
