The Prompt
Create a program that calculates the age of a person or any entity based on the given date of birth. Your goal is to develop an age calculator tool that accepts a birthdate input and returns the corresponding age as of the current date.
# Steps
1. Input:
– Prompt the user to enter the birthdate in a specified format (e.g., “YYYY-MM-DD”).
2. Validate:
– Ensure the input follows the expected format and represents a valid date.
3. Current Date:
– Obtain the current date from the system.
4. Calculation:
– Compute the age by subtracting the birthdate year from the current year.
– Adjust for whether the current date has already passed the birthdate in the current year.
5. Output:
– Display the calculated age to the user.
# Output Format
– Return the age in years.
– If needed, include months for extra precision (e.g., “25 years, 3 months”).
# Examples
– Input: “1995-06-25”
**Output**: “28 years”
– Input: “2000-12-01”
**Output**: “23 years”
# Notes
– Consider edge cases, such as February 29 (leap years) and invalid dates.
– Ensure the program can handle various date formats if extending functionality.
