A ferramenta \u00e9 gratuita e n\u00e3o exige cadastro. Para apurar uma semana com pausas, use a <a href=\"https:\/\/simcalculo.com\/pt-br\/calculadora-horas-trabalhadas\/\">calculadora de horas trabalhadas<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Como usar a calculadora de horas<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Em <strong>Somar e subtrair<\/strong>, informe uma dura\u00e7\u00e3o por linha, como 02:30 para duas horas e meia ou 02:30:45 para incluir segundos. Escolha somar ou subtrair em cada linha e adicione at\u00e9 20 dura\u00e7\u00f5es. Campos vazios s\u00e3o ignorados; para informar zero, use 00:00.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Em <strong>Entre hor\u00e1rios<\/strong>, informe in\u00edcio e fim no rel\u00f3gio de 24 horas. Se o fim ocorrer no dia seguinte, marque essa op\u00e7\u00e3o. Em <strong>Converter decimal<\/strong>, informe um n\u00famero como 8,5 para obter 08:30:00. Todos os modos apresentam horas decimais, minutos, segundos e as etapas da conta.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Como somar horas, minutos e segundos<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">O tempo usa base 60: <strong>60 segundos = 1 minuto<\/strong> e <strong>60 minutos = 1 hora<\/strong>. Para calcular, transformamos cada dura\u00e7\u00e3o em segundos: <strong>total = horas \u00d7 3.600 + minutos \u00d7 60 + segundos<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Exemplo: <strong>02:30:45 + 01:45:15 = 04:16:00<\/strong>. As dura\u00e7\u00f5es correspondem a 9.045 e 6.315 segundos. A soma \u00e9 15.360 segundos: quatro horas e 16 minutos. Para 45 minutos + 30 minutos, o total \u00e9 75 minutos, equivalente a 1h15.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Como subtrair dura\u00e7\u00f5es<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Escolha \u201cSubtrair (\u2212)\u201d na linha que deve ser retirada. Por exemplo: <strong>05:15:45 \u2212 03:20:30 = 01:55:15<\/strong>. A ordem importa: 01:00 \u2212 02:00 resulta em \u221201:00:00. O sinal negativo se refere \u00e0 dura\u00e7\u00e3o inteira, n\u00e3o a um hor\u00e1rio de rel\u00f3gio.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Como calcular o tempo entre dois hor\u00e1rios<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Subtra\u00edmos o in\u00edcio do fim. Das <strong>08:00 \u00e0s 17:30<\/strong> h\u00e1 <strong>9h30<\/strong>. Das <strong>22:00 \u00e0s 06:00 do dia seguinte<\/strong>, somamos 24 horas ao fim antes de subtrair: 30h \u2212 22h = <strong>8 horas<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Hor\u00e1rios iguais representam zero quando s\u00e3o do mesmo dia e 24 horas quando a op\u00e7\u00e3o \u201cdia seguinte\u201d est\u00e1 marcada. A ferramenta n\u00e3o presume a passagem da meia-noite: a escolha fica expl\u00edcita.
