It is not case sensitive. The default for annual data is the end of the year, which also differs from dateutil. :qmrr )re IGNORECASEVERBOSEsearch _q_patternreplacelowersplit_quarter_to_dayupperr% _m_pattern _month_to_dayr( _y_patternrdatetime) timestr parserinfokwargsflagsyr-monthdayr&r.s r' date_parserrE@s MMBJJ &E yyWe,ooc"%++-33C8!$QWWY/ s1v :w .ooc"%++-33C8!"1779- s1v A;5A: 1HC :w . s7|7-f--   T5# ..r)c Ztjtjz}|j}tjt ||rd}d}nZtjt ||rd}d}n:tjt||rd}|dz }|r|dz }d}ntd|ztt|jd d j|\}}|C|j}tt|jd d j|\}} n |s td |||zz}||z|dz z} tjt|dz||D cgc] } t!| } } t!|g|dz|z z| z} | t!|g| zz} |dk7rtj"tj$d|dz||z dz j'd } tj(tj$||dzj'd | f} tj(| tj$d| dzj'd f} t+| | D cgc]"\} }d j-| |t/|g$}} }|S| }|Scc} wcc}} w) a Returns a list of abbreviated date strings.
