This year's contest is the 24th edition of the Junior Eurovision Song Contest.
Unlike the adult Eurovision Song Contest, viewers can vote for their own country, meaning Polish viewers can support 14-year-old Sas.
The show will begin at 9 p.m. Warsaw time on Saturday. It will be broadcast in Poland by public broadcaster TVP and streamed online through Junior Eurovision's official channels.
The first voting window will open at 11:59 p.m. on Friday and run until 8:59 p.m. on Saturday.
To vote, viewers should visit the competition's official website at jesc.tv, watch a recap of the performances from rehearsals, select their three favourite songs and confirm their choices, TVP said.
A second voting window will open after Saturday's performances. Once the final contestant has performed, viewers will have about 15 minutes to vote.
Online votes from viewers around the world will be tallied and converted into points on a proportional basis. They will account for 50 percent of the final score, while the other half will come from national juries in participating countries.
The total scores and the winner of the Junior Eurovision Song Contest 2026 will be announced at the end of the broadcast.
Poland has a strong record in the competition.
Sara James finished runner-up at the 2021 Junior Eurovision in Paris with "Somebody."
Viki Gabor won the 2019 contest with "Superhero," a song carrying an environmental message, while Roxana Węgiel won in 2018 with "Anyone I Want to Be."
Held since 2003, Junior Eurovision is a song competition for performers aged 9 to 14, organised by the European Broadcasting Union. It follows a format similar to the Eurovision Song Contest, the larger competition for adult performers.
