August 18 Holidays

National Fajita Day celebrates the Tex-Mex dish of grilled skirt steak, onions, and peppers served with flour tortillas — a preparation traced to Mexican vaquero ranch workers in South Texas in the 1930s and popularized by Ninfa Rodriguez Laurenzo at her Houston restaurant in 1973. National Couples Day was created to celebrate romantic partnerships and to encourage couples to take a dedicated day to appreciate each other — to put down their phones, share a meal, and mark the relationship they are building. Indonesia Constitution Day marks August 18, 1945, when Indonesia adopted its first constitution — one day after independence was proclaimed, establishing the legal framework of the new republic. Long Tan Day marks August 18, 1966, when Australian and New Zealand forces fought the Battle of Long Tan in Vietnam — a six-hour engagement in which 108 ANZAC soldiers held off a force of approximately 2,500 Viet Cong and North Vietnamese Army troops. A sizzle, a partnership, a constitution, and a six-hour battle.
