When does third trimester begin?

The majority of websites say it's 28, but some have said third trimester begins at 27 and a couple have said 29...

I'm more inclined to believe it starts at week 28, but I'd love it to start at 27!

Tried to find the answer on the NHS website and couldn't. Anyone know?

Well if you divide 40 weeks by 3 (TRImester) it's around 26 weeks ...however this division is not a real division just man made .... hence nothing is going to happen when the clock strikes 12 on the eve of your third trimester.
