"9:45" can be read as "nine forty-five" (顺读) or "forty-five nine" (逆读) in Engpsh.

The origin of this format is from the practice of using the 12-hour clock system, where the hours are numbered from 1 to 12 and the minutes are numbered from 0 to 59. In this system, 9:45 is read as "nine forty-five" when the time is in the morning or afternoon, but it is read as "forty-five nine" when the time is at night.

Examples:

"The meeting starts at 9:45." (顺读)
"I'll see you at 9:45 tonight." (逆读)
