To clarify your question, you asked "how many hours until 1 today." Assuming you mean how many hours until 1:00 AM today, since the current time is 2:23 PM UTC on August 22, 2025, 1:00 AM today (August 22) has already passed. If you meant 1:00 AM the next day (August 23), then the hours until 1:00 AM tomorrow would be the time from now (2:23 PM) until 1:00 AM next day. Calculating from 2:23 PM (14:23) today to 1:00 AM tomorrow:

• From 2:23 PM to midnight is 9 hours and 37 minutes
• From midnight to 1:00 AM is 1 hour
• Total is 10 hours and 37 minutes approximately.

So, there are about 10 hours and 37 minutes until 1:00 AM tomorrow. If you meant 1:00 PM today, then that time has also passed by about 1 hour and 23 minutes. Please specify if you want the count until 1:00 AM or 1:00 PM, and for which day (today or tomorrow) or your time zone. I can provide precise calculation then.
