The true answer is that there is no general answer. It depends on a lot of different factors.
When during the day or which day of the week you book your ticket usually doesn’t influence the price that much (while it can indeed affect price to some extent).
Sometimes you can see some article where they have “analysed X amount of data” and found that you should book your ticket Y weeks before departure.
The problem with these articles, and what they usually neglect, is that it all depends on which route you are flying - and when during the year you are leaving.
Say we are living in Gothenburg and want to fly to London. If we neglect when during the year we are actually leaving, the graph below gives us an idea about how long in advance we should book our ticket.
Average lowest price from Gothenburg to London
In this graph we can see that about 21 weeks before departure seem to be a good time to book the ticket.
Now, if we assume that we are leaving in August, the most popular month, the graph would look very different.

Suddenly about 35-40 weeks before departure seem to be the time to book your ticket.
If we then instead intend to fly there in February, the least active month, we have another graph.
Average lowest price from Gothenburg to London
Here it looks like 9 weeks before departure would be the best, and 40 weeks before looks actually quite expensive.
On the flip side though, if you are going when few others are going, you may actually gain from waiting and not book your ticket too early.
But there is a lot more to it.
If we instead look at a flight to Sydney, with no care for when during the year we are flying, the graph looks very different from London.

For such a long flight you are typically better off booking your ticket as early as possible. Although, that is not always true either, as it may depend on tourist season at the destination, special events, etc.
