According to the website https://www.qppstudio.net/public-holidays-by-date/today.htm, today is a national holiday in Bangladesh (National Mourning Day), India (Independence Day), Paraguay (Ascunsión Foundation Day), and South Korea (also Independence Day) — none of which have notably red flags. It’s also Assumption Day in a whole flock of countries, with red flags popping up in Austria, Chile, France and a bunch of its former colonies, Liechtenstein, Luxembourg, Madagascar, Malta, Monaco, Poland, Portugal, Romania, and Vanuatu, but the one with the most red is Switzerland.
