May 22, 2020, was in the past relative to today, May 17, 2025. To calculate how many days have passed since May 22, 2020, until May 17, 2025:

• From May 22, 2020, to May 22, 2025, is exactly 5 years.
• 5 years = 5 × 365 days + 1 or 2 leap days (2020 was a leap year, but May 22 is after Feb 29, so 2020 leap day counts; 2024 is also a leap year)
• Leap years between 2020 and 2025: 2020 and 2024 → 2 leap days
• Total days in 5 years = (5 × 365) + 2 = 1825 + 2 = 1827 days
• Since today is May 17, 2025, which is 5 days before May 22, subtract 5 days:
• Total days from May 22, 2020, to May 17, 2025 = 1827 - 5 = 1822 days

Answer: It has been 1,822 days since May 22, 2020.
