Description

Hi, I found several FPs when parsing strings. It appears single letters parse somehow?

In [2]: from dateparser import parse                                                                                                                                                                                                                                                                                                

In [3]: parse("A")                                                                                                                                                                                                                                                                                                                  
Out[3]: datetime.datetime(2020, 1, 26, 0, 0)

In [4]: parse("B")                                                                                                                                                                                                                                                                                                                  
Out[4]: datetime.datetime(2020, 8, 23, 0, 0)

In [5]: parse("A").isoformat()

In [6]: parse("B").isoformat()                                                                                                                                                                                                                                                                                                      
Out[6]: '2020-08-23T00:00:00'

In [7]: parse("C").isoformat()

Research direction

Start by reproducing the reported parse("A"), parse("B"), and parse("C") results in the dateparser test environment, then trace the parser path handling single-letter input. Confirm the intended behavior for such inputs with the maintainers; done should include regression coverage showing that arbitrary single letters are not falsely parsed as dates.
