It is not case sensitive. The default for annual data is the end of the year, which also differs from dateutil. ú:ÚÚqÚmérr )ÚreÚ IGNORECASEÚVERBOSEÚsearchÚ _q_patternÚreplaceÚlowerÚsplitÚ_quarter_to_dayÚupperrÚ _m_patternÚ _month_to_dayr!Ú _y_patternrÚdatetime) ZtimestrZ parserinfoÚkwargsÚflagsÚyr$ZmonthZdayrr%rrr Ú date_parser@s     r8c sÌtjtjB}| ¡}t t||¡r,d}d‰nPt t||¡rDd}d‰n8t t||¡rpd}|d7}|rj|d7}d‰n td|ƒ‚t t |  d d ¡  ˆ¡ƒ\}}|d urÆ| ¡}t t |  d d ¡  ˆ¡ƒ\}}n(|sÒtd ƒ‚|||}|||d}d d„t  t|d|ƒ|¡Dƒ} t|ƒg|d|| } | t|ƒg|} ˆdkrÄt  t  d|d¡||d¡ d¡} t jt  ||d¡ d¡| f} t j| t  d|d¡ d¡f} ‡fdd„t| | ƒDƒ} n| } | S)a“ Returns a list of abbreviated date strings.
