Limitations

Current limitations based on the implementation:

• JalaliDataFrameAccessor requires at least one column of jdatetime objects and raises if none are present.
• JalaliResampler expects a pd.DatetimeIndex as index; otherwise it raises.
• jalali_date_range requires at least two of start, end, periods; if all three are provided, freq is required.
• to_jalali_datetime parses a fixed set of formats unless format is provided explicitly.
• JalaliDatetimeArray stores values in an object array, which can be slower than native datetime64 operations for large datasets.

If you hit a limitation, open an issue with a minimal reproduction case.
