Few issues

• There are some unused variables, see https://app.codacy.com/gh/PyThaiNLP/pythainlp/pull-requests/998/issues
• Variable and function names should follow conventions in PEP 8 https://peps.python.org/pep-0008/#function-and-variable-names
  • For example, instead of StartY, use start_y.
• Some variable names have a prefix i, probably as a convention from VBA to indicate that this variable is an Integer. Python doesn't have that convention. Actually, i here is for "input", still redundant (except in the context of i_date, since date is already used by Python)
  • So instead of iYear, we can use just year.
• The use of unnecessary XLMod() instead of a standard % for modulo
