Document naming convention
Good pratice is follow ISO 8601 when you need to include Date in you filename. On wikipedia there is free article about that.
With one exception don't use special character for date delimiter.
Good format
For 11. May 2019. use this format

- two numbers for year
2019-05-11 minus sign as delimiter {{{ 2019/05\11 - slash and backslash as delimiter {{{20 19 05 11 - space is delimiter
