Hi Graham c
Ok its a rolling 180 days which you can use any 90 in any combination you like, so see below dates I have added into my app on the phone called "Schengen calculator free"
Lets say you enter Spain on 15th April that is day 1 if you drive then whatever landing point would be day 1, you leave on 31st May that meens you have 43 days left in the rolling 180 to use.
Lets say you now arrive back 15th September this would be day 1 as your rolling 180 days finished on the 30th August so you are back to 90 in 180 days, you leave on the 17th October you would be left with 57 days to use if not your 180 days rolls out 19th January 2022.
So for what you are doing you are well under the days, download the calendar app its great keeps you right, hope this helps
