Meaning of 'on end' in a particular sentence

[Tamara]

Hi

You could study it for weeks on end prior to coding a simple procedure.

I suppose here on end = through.

Could you validate it or give a better 'translation' of the phrase on end in the above context?

Hi Tamara,

The suggestion here is that this study would go on week after week. 'On end' implies never stopping.
