To determine how much longer until 12 AM (midnight), it depends on the current local time. Given that the current UTC time is approximately 5:38 PM on Friday, September 12, 2025, the time remaining until 12 AM depends on the local timezone. For example, if you are in the UTC timezone, there are about 6 hours and 22 minutes remaining until midnight. However, the exact time left varies by location. Would you like me to calculate the exact time remaining until 12 AM based on a specific timezone or your current location?
