A parser to convert natural language date and time specification into a DateTime.

The parser recognizes a variety of phrases related to dates and times, such as "next Monday," "tomorrow at 5 PM," or "3 weeks from now." This parser converts these expressions into structured DateTime objects, making them usable in scheduling applications, reminders, or other time-based software.

• Simple Relative Dates: "today," "tomorrow," "yesterday."
• Day of the Week Expressions: "next Monday," "last Friday."
• Complex Relative Time Expressions: "in 3 days," "2 weeks from now," "4 months ago."
• Combined Date and Time Expressions: "next Thursday at 10 AM," "tomorrow at 5:30 PM."
