Articulating this question is going to be a mess but here we go; How does capital gains tax work if I have been accumulating LTR shares every month since August?

Is the 1 year count down initiated from the initial acquisition of shares, meaning if my first purchase of LTR shares was August, would all shares I accumulate up until August the following year be eligible for 1/2 capita gains tax; or would each acquisition of shares be treated differently: if I had a balance of 20k shares August but purchased another 100k shares throughout October-December then 20k would be eligible for 1/2 capital gains tax August, whilst the other 100k shares eligible throughout October-December.
