My situation is similar to Rizwan and I asked about this in another page but didn't really get a celar answer.
I know the guidance in April 2016 states you can calculate from the date of issue as long as your entry is less than 180 days later.
however there is another guidance which is released in 24th November 2016 and it says in page 4 section 5 (
If you entered the UK with a visa several weeks or more after the date from which it was valid for use, you may need to apply for an extension of stay to complete the relevant qualifying period.) I am not sure if the moderators have seen this latest guidance or not as they always seem to be referring to April guidance.? does this later document cancel the April guidance or am I looking at the wrong document? the link to November guidance is:

would appreciate if someone could read page 4 and advice please as I am terribly confused.
