Fixing the 'first week day' issue in one part and leaving the rest in the inconsistent state will only make it harder to fix it properly later on.

What I find strange is that there are two different "Last week" groups separated by the groups "Thursday", "Wednesday", and "Tuesday". It's like there are two different "last" weeks, with a few days in between which belong to the "current" week. This looks like a broken mess to me, but considering that nobody else seems to consider this a bug, maybe I'm wrong after all ;-)

I've changed the logic now. When the month aren't the same I print Last Month, Two Month Ago and so on as long as the year stays the same. Everything older will have the title Older. Maybe we can shorten that to lets say 4 month or so.

But this doesn't solve the first day of week problem. Maybe we should rename Last Week to One Week ago? Then it doesn't matter which day was the first day of the week.
