What it is Filled

July 15, day 196 (day 197 in leap years) of the year in the Gregorian calendar, with 169 days remaining in both common and leap years. July 15 is the UN World Youth Skills Day and St Swithin s Day in English folklore, and in Turkey it is commemorated by the government as Democracy and National Unity Day, marking the failed coup attempt of 2016; it is also the anniversary of the capture of Jerusalem by crusaders in 1099.
