through
Expresses movement through something from one side to the other. Often used to reinforce 'durch' (through).
Wir mussten durch den engen Tunnel hindurch, um auf die andere Seite des Berges zu gelangen.
We had to go through the narrow tunnel to get to the other side of the mountain.
throughout
Describes that something lasts for an entire period of time; during the whole time.
Er hat die ganze Nacht hindurch gearbeitet, um das Projekt fertigzustellen.
He worked throughout the whole night to finish the project.
The word is made up of 'hin' and 'durch'. 'Durch' describes movement through something, while 'hin' emphasizes movement from one point to another. It strengthens the idea of crossing or passing through something completely.
Der Weg führt mitten durch den Wald hindurch.
The path leads right through the middle of the forest.
With spatial movement, 'hindurch' is often used together with the preposition 'durch'. In this structure, 'durch' comes before the place and 'hindurch' comes at the end of the phrase to emphasize the movement.
Wir sind durch das ganze Tal hindurch gewandert.
We hiked through the entire valley.
When it describes a duration of time, 'hindurch' often comes after the noun that indicates the time span. It then functions like a postposition.
Den ganzen Sommer hindurch hat es kaum geregnet.
Throughout the whole summer, it hardly rained.
over / about
For an event that extends across an entire period of time, both über and hindurch are possible. Über is the neutral and usually more idiomatic choice, whereas hindurch emphasizes the full duration more strongly and often sounds more emphatic. In everyday speech, über is usually sufficient.
Den ganzen Winter hindurch blieb der See zugefroren.
The lake remained frozen throughout the entire winter.
Über den ganzen Winter blieb der See zugefroren.
The lake remained frozen throughout the entire winter.
