What happened to flags on 31 July
One flag in the atlas carries this date. The sentence under it is where that is written down, in its own article.
- Iraq 1963
This basic tricolour has been in use since its adoption on 31 July 1963, with several changes to the green symbols on the central white stripe; the most recent version adopted on 22 January 2008 bears the takbīr rendered in dark green and removes the three green stars present since 1963.

How a day gets onto this site
A flag is here because a sentence in its own English Wikipedia article puts it on this date, and that sentence is printed above. Nothing was worked out from a year, and nothing was written for the occasion. Every sentence names the article it came from and the version of that article it was read in, so you can go and check it.
The calendar is still short rather than full. A third of the year has no page here, because a flag only gets a day when a sentence in its article puts something on one, and plenty of articles never do. Nothing is invented to fill the gap.
