To calculate how many days have passed since January 1, 2023, up to May 16, 2025:

1. From January 1, 2023, to January 1, 2024 = 365 days (2023 is not a leap year)
2. From January 1, 2024, to January 1, 2025 = 366 days (2024 is a leap year)
3. From January 1, 2025, to May 16, 2025:

• January: 31 days
• February: 28 days (2025 is not a leap year)
• March: 31 days
• April: 30 days
• May: 16 days
  Total = 31 + 28 + 31 + 30 + 16 = 136 days

Now, add all these together: 365 + 366 + 136 = 867 days So, 867 days have passed since January 1, 2023, up to May 16, 2025.
