(DOMINGO É 13) The story behind this trend in Social Media today
02-10-2026
I’ll look up what’s driving the “Domingo é 13” trend today.“Domingo é 13” is a Brazilian election slogan circulating ahead of the first round of the 2026 general election, set for Sunday, 4 October.In Brazil, each party gets a fixed ballot number. The Workers’ Party (PT) and its presidential candidate, Luiz Inácio Lula da Silva, run under 13; the main rival associated with the phrase “dois patinhos na lagoa” (two little ducks on the pond) is Flávio Bolsonaro of the Liberal Party, under 22. Campaign messaging has been playing on that number: posts in late September used lines such as “faltam 13 dias pra votar 13,” counting down to election day and tying the date to the ballot number.The exact catchphrase “e domingo é 13, confirma,” often followed by a little jingle sound rendered as “tilintiltilim,” spread as a short video clip that supporters shared and remixed. It is not a claim that the calendar date is the 13th. It means that on election Sunday the vote to confirm is 13.The line also got a boost from sports television. On 28 September, during Band’s Apito Final, commentator Craque Neto repeatedly stressed “dia 13” while talking about a book launch scheduled for the 13th, then joked with a producer about “dois patinhos na lagoa.” Viewers and outlets read the bit as a wink at the 13-versus-22 presidential race, and clips of it fed the same online wave.So the trend is campaign wordplay in the final stretch before the 4 October vote: Sunday is when people vote, and 13 is the number being pushed.
