< p > WordPress offers you the ability to create a custom URI structure for your permalinks and archives . The following & #8220;tags” are available:</p>
< ul >
< li >< code >% year %</ code > --- The year of the post , 4 digits , for example 2003 </ li >
< li >< code >% monthnum %</ code > --- Two digit month , for example 05 </ li >
< li >< code >% day % </ code >--- Day of the month , for example 28 </ li >
< li >< code >% postname %</ code > --- A sanitized version of the title of the post . So & quot ; This Is A Great Post !& quot ; becomes & quot ; this - is - a - great - post & quot ; </ li >
< li >< code >% category %</ code > --- Category name of the post . For example & quot ; general & quot ; . < strong > Not done yet . </ strong ></ li >
</ ul >

< p > So for example a value like < code >/% year %/% monthnum %/% day %/% postname %/</ code > could give you a permalink like < code >/ 2003 / 05 / 23 / my - cheese - sandwich </ code > . For this to work you ' ll need mod_rewrite installed on your server for the rule generation rule to work below . In the future there may be other options . </ p >
