One difference is that Powys has opted to end the summer term on 16 July 2027, before the start of the Royal Welsh Show which runs from Monday 19 to Thursday 22 July 2027.
Un gwahaniaeth yw bod Powys wedi dewis dod â thymor yr haf i ben ar 16 Gorffennaf 2027, cyn dechrau Sioe Frenhinol Cymru, a gynhelir rhwng dydd Llun 19 Gorffennaf 2027 a dydd Iau 22 Gorffennaf 2027.
