[Solved] Formula to find week numbers from the Total [closed]


You could take a bitwise AND & with the day value and take this day.

const
    days = { Monday: 1, Tuesday: 2, Wednesday: 4, Thursday: 8, Friday: 16, Saturday: 32, Sunday: 64 },
    getDays = value => Object.keys(days).filter(day => value & days[day]);

console.log(getDays(127)); // All Days
console.log(getDays(80));  // Friday, Sunday
console.log(getDays(7));   // Monday, Tuesday, Wednesday
