  Hey Robert 👋, congratulations on solving this challenge

  Your date validation is good, but if you want to calculate age in more concise and readable code you can look at my following code:

  function calculateAge(day, month, year) {
    const today = new Date();
    const birthDate = new Date(year, month - 1, day);
  
    //Date Validation
    const isDayValid = birthDate.getDate() === day;
    const isMonthValid = birthDate.getMonth() === month - 1;
    const isYearValid = birthDate.getFullYear() === year;
  
    if (!isDayValid || !isMonthValid || !isYearValid) {
      isInputValid.value = false;
      return;
    }
  
    //calculating difference of current date and birthdate
  
    let ageYears = today.getFullYear() - birthDate.getFullYear();
    let ageMonths = today.getMonth() - birthDate.getMonth();
    let ageDays = today.getDate() - birthDate.getDate();
  
    if (ageMonths <= 0) {
      ageMonths += 12;
      ageYears--;
    }
  
    if (ageDays < 0) {
      const lastMonthDate = new Date(
        today.getFullYear(),
        today.getMonth(),
        0
      ).getDate();
      ageDays += lastMonthDate;
      ageMonths--;
    }
  
  
    //Age:
    console.log(ageYears, ageMonths, ageDays);
  }
  

  I hope this will help

  Regards,

  Shahjahan
