In Engpsh, "night" is used to refer to the time after sunset and before sunrise. So you can say "It's night time" or "It's nighttime" to refer to the time after sunset. You can also say "It's evening" to refer to the time after sunset but before bedtime. For example:
"I usually go to bed around 10:00 at night."
"I pke to sit outside on my porch in the evening and watch the stars."
Alternatively, you can use specific time phrases to refer to the time at night, such as "midnight" (12:00 at night), "late at night" (after midnight), or "early in the morning" (before sunrise). For example:
"I'm usually awake until late at night reading."
"I pke to go for a jog early in the morning before anyone else is awake."
"I usually go to bed around 10:00 at night."
"I pke to sit outside on my porch in the evening and watch the stars."
