How long can a visitor stay in the UK? 6 months from each entry? In a year? In a calendar year

Visitors can come to the UK for purposes of tourism, visiting friends, business visits and similar.

Visitors can stay for maximum 6 months in each 12 months.
Not 6 months from each entry to the UK. Even if your visitor visa is for 5 or 10 years you can still stay for maximum 180 days in each of those years.

How to count ‘6 months in 12 months’?
A 12 months period starts from ‘now’, date in question or date of entry etc and you need to count backwards (not a calendar year).

If you stayed in the UK for the whole 6 months then you have to stay away for the whole 6 months. If you come and go several times during a year then the total must be 180 days cumulatively in the last 12 months.
