Apple Calendar cannot open a CSV file: on iPhone, iPad and Mac it imports calendar files in the .ics format only. Upload your spreadsheet here — a rota, a term calendar, a season of fixtures — and each row becomes an event in an .ics file that Calendar adds in one step.
On iPhone and iPad, tap the downloaded file and choose which calendar the events go into. On a Mac, double-click it. No extra app is needed.
Add the events to an iCloud calendar on one device and they appear on the others.
Use the columns you already have. The headers are read and matched to title, date, time, location and description for you.

Three events in Apple Calendar on 7, 14 and 21 November, each with its kick-off time and the ground as the location.
