Quick FAQ
in the morning, in the afternoon, in the evening, but at night?This is primarily an idiomatic convention in English. Morning, afternoon, and evening are generally perceived as broader, more fluid periods, hence in. Night, while a period, is often treated as a more distinct, singular point in the daily cycle for general reference, aligning with at. There isn't a deep logical rule; it is simply how English evolved.
the with morning, afternoon, evening, and weekend?Yes, for general reference, the definite article the is almost always required: in the morning, in the afternoon, in the evening, on the weekend. The only exception among these is at night, where the is typically omitted for general statements.
in the night?Yes, but its meaning is more specific. In the night usually implies something happened during the night, often unexpectedly or when one would normally be asleep. For example, I heard a strange sound in the night. For general statements about the period of darkness, use at night.
on the weekend and at the weekend?Yes, primarily a regional one. On the weekend is the standard and most common form in American English. At the weekend is more prevalent in British English. Both are grammatically correct and widely understood globally. Learners can choose one to maintain consistency.
On weekends (without the and with s at the end) means every weekend or regularly on weekends. For example, I play soccer on weekends means you play soccer every Saturday and/or Sunday. This contrasts with on the weekend, which usually refers to a specific single upcoming or past weekend.
For combinations of a specific day of the week and a part of the day, you use on. For example, on Monday morning, on Friday evening. The on takes precedence because you are referring to a specific day. This topic is covered in more detail in lessons about days of the week.
every morning or every night?In these cases, you do not use any preposition. Simply say every morning, every afternoon, every evening, or every night. For example, I drink tea every morning. Similarly, each morning or each evening works the same way.

FAQ (8)
It's a historical exception. 'Morning' is seen as a duration (a box of time), while 'night' was historically seen as a single point in time.
Yes, but only for specific events, like 'I heard a noise in the night.' For habits, always use 'at night'.
Both are correct. 'On' is American; 'At' is British. Use the one that matches the dialect you are learning.
No. We say 'at night', not 'at the night', unless we are talking about one specific night.
Use 'at'. 'At noon'.
Use 'on'. 'On Monday morning'. The day of the week always takes 'on'.
Not quite. 'Evening' is usually before you go to bed (5 PM - 9 PM). 'Night' is when you sleep or when it is very late.
No, say 'on weekends' (plural) or 'on the weekend' (singular).
