A simple Python script to add time durations to a given start time, with support for 12-hour and 24-hour formats and optional weekday calculations.

• Flexible Time Addition: Add any duration (hours and minutes) to a start time in 12-hour format (e.g., "8:30 AM").
• 12h/24h Conversion: Handles conversions between 12-hour (AM/PM) and 24-hour formats.
• Weekday Tracking: Optionally specify a starting day to calculate the resulting day after adding time (e.g., "Monday" → "Tuesday").
• Clean Output: Returns formatted time with proper AM/PM, minutes padded with zeros, and day information (e.g., "next day" or "3 days later").

Run the script with a start time, duration, and optional starting day:

add_time("8:30 AM", "2:45")  # Returns "11:15 AM"
add_time("11:30 PM", "3:45", "Monday")  # Returns "3:15 AM, Tuesday (next day)"
add_time("11:59 PM", "24:05", "Wednesday")  # Returns: "12:04 AM, Friday (2 days later)"

• Input Parsing: Takes a start time (e.g., "8:30 AM"), duration (e.g., "2:45"), and optional weekday (e.g., "Monday").
• Time Calculation: Converts the start time to 24-hour format, adds the duration, and handles minute/hour overflow.
• Day Tracking: If a weekday is provided, calculates the resulting day based on the duration (e.g., adds days if time exceeds 24 hours).
• Output Formatting: Returns the result in 12-hour format with proper AM/PM and day information.

• The script assumes valid input formats (e.g., "HH:MM AM/PM" for start time, "HH:MM" for duration).
• Weekdays are case-insensitive (e.g., "monday" or "Monday" both work).
