I can use the information provided to answer questions about age calculation or the specific people listed.
I can tell you:
- The simple formula for age calculation: Age=(Current Date−Birth Date)
- That Donald Trump will be 79 years old in 2025.
- That the United States will be 249 years old in 2025.
- The difference in age counting between the Western system (age starts at 0) and the East Asian system (age starts at 1 and increases on New Year’s Day).
What birth date would you like to calculate the age for? Or, would you like to know the age of one of the people listed in the table (Trump, Taylor Swift, etc.)?
If you have a specific question not covered in the text (like someone who is not on the list), I will need to use a search.
