Como chegamos a 52 semanas no ano?

A origem do calendário

Culturas antigas começaram a medir o tempo há mais de 11 mil anos, observando o sol e a lua.

Influência religiosa

O controle do tempo era essencial para práticas religiosas, como orações em horários específicos.

Calendário juliano

Criado por Júlio César em 46 a.C., calculava o ano com 365,25 dias, mas tinha pequenas imprecisões.

Problema de acúmulo de dias

No século XVII, os erros acumulados do calendário juliano somavam 10 dias.

O Papa Gregório XIII entra em ação

Em 1582, ele ajustou o calendário, criando o sistema de anos bissextos e corrigindo a discrepância.

Resistência e adoção mundial

Países como Inglaterra e China demoraram séculos para aceitar o calendário gregoriano.

Calendário Milanković

Um refinamento do sistema de anos bissextos foi proposto em 1923 para maior precisão.

Uso globalizado

O calendário gregoriano se tornou o padrão global, embora algumas culturas mantenham sistemas alternativos.
