'Hassen' is often used with a direct object in the accusative. The structure 'es hassen, etwas zu tun' (to hate doing something) or 'es hassen, wenn ...' (to hate it when ...) is also very common for describing an activity or situation that you don't like.
Ich hasse diese laute Musik.
I hate this loud music.
The verb 'hassen' (to hate) is directly connected to the noun 'der Hass' (hatred). When someone hates a person or thing, they feel hatred.
Sein Hass auf das System war in jedem seiner Worte spürbar.
His hatred of the system was noticeable in every one of his words.
In this meaning, 'hassen' (to hate) is an extremely strong word. It describes deep emotional rejection and hostility and should be used carefully, especially when referring to people.

The two families have hated each other for generations.
When 'hassen' (to hate) refers to everyday things or activities (e.g. getting up early, spiders, waiting), it is usually a colloquial exaggeration and means 'not liking something at all.' The context makes it clear that it is not deep, genuine hatred.
Ich hasse Montage, weil die Woche dann wieder von vorne anfängt.
I hate Mondays because then the week starts all over again.

'lieben' and 'hassen' are clear opposites. 'lieben' expresses strong positive feelings, for example toward a person, a thing, or an activity. 'hassen' expresses very strong negative feelings or strong dislike. Both words are stronger than 'mögen' (to like) and 'nicht mögen' (to not like). In everyday language, 'hassen' is sometimes used as an exaggeration, for example about food, noise, or tasks. Even so, it sounds very strong. If you only want to say that something is unpleasant, 'nicht mögen' is often milder.
