My knowledge of the Harry Potter timeline isn't great, but an exchange in Half-Blood Prince caught my eye:

“They’ve known each other a year,” said Ron, who looked oddly groggy and was staring at the closed door.
“Well, that’s not very long! I know why it’s happened, of course. It’s all this uncertainty with You-Know-Who coming back, people think they might be dead tomorrow, so they’re rushing all sorts of decisions they’d normally take time over. It was the same last time he was powerful, people eloping left, right, and center —”
“Including you and Dad,” said Ginny slyly.
“Yes, well, your father and I were made for each other, what was the point in waiting?” said Mrs. Weasley.

This doesn't seem to sit well with the “Your father and I had been for a nighttime stroll” joke in Goblet of Fire, which suggests that Mr and Mrs Weasley were very well acquainted during their time at Hogwarts.

Now, I fully admit that this is based on a joke and some innuendo, but does this actually sit well with the timeline? As I understand it, Voldemort was last in power roughly when Ron was born and Ginny's line suggests that Mr and Mrs Weasley got together while he was still in power. Does this mean that Voldemort was in power for so long that Mr and Mrs Weasley had the time to graduate, rush off, and have seven kids before he fell? And if so, does this timeline align with when Mr and Mrs Weasley actually graduated?
