I've encountered an error converting an integer to text in JavaScript

Question

Everything on my HTML code is working just fine apart from a JavaScript error I am getting. Whenever I try to convert an integer such as the current day, it defaults to the highest possible value.

I always get a value of "Aujourd'hui c'est samedi, le trente–et–un décembre, 2015" when I run this: 

 <html> <title> French Review - Time and Dates </title> <head> <style> div.img { margin: 5px; padding: 5px; border: 1px solid #0000ff; height: auto; width: auto; float: left; text-align: center; } div.img img { display: inline; margin: 5px; border: 1px solid #ffffff; } div.img a:hover img { border: 1px solid #0000ff; } p { font-weight: normal; font-family: Verdana; } </style> </head> <body> <center> <img src="Header.png" width=1250></img> <div class="img"> <img src="10-30.png" alt="10:30 AM" width="220"> <p id="answer">Quelle heure est-il?</p> <button type="button" onclick="document.getElementById('answer').innerHTML = 'Il est dix heure et demie du matin.'"> Reveal answer</button> </div> <div class="img"> <img src="1-15.png" alt="1:15 PM" width="220"> <p id="answer2">Quelle heure est-il?</p> <button type="button" onclick="document.getElementById('answer2').innerHTML = 'Il est une heure et quart du l&#8217;après-midi.'"> Reveal answer</button> </div> <div class="img"> <img src="5-45.png" alt="5:45 PM" width="220"> <p id="answer3">Quelle heure est-il?</p> <button type="button" onclick="document.getElementById('answer3').innerHTML = 'Il est six heure moins le quart.'"> Reveal answer</button> </div> <div class="img"> <img src="12-00.png" alt="12:00 AM" width="220"> <p id="answer4">Quelle heure est-il?</p> <button type="button" onclick="document.getElementById('answer4').innerHTML = 'Il est midi.'"> Reveal answer</button> </div> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <div class="img"> <img src="Today.png" alt="Today" width="220"> <p id="answer5">Quelle est la date?</p> <button type="button" onclick="document.getElementById('answer5').innerHTML = 'C&#8217;est '"> Reveal answer</button> </div> <div class="img"> <img src="Today.png" alt="Today" width="220"> <p id="answer6">Quelle est le mot?</p> </div> <div class="img"> <img src="Tomorrow.png" alt="Tomorrow" width="220"> <p id="answer7">Quelle est la date?</p> </div> <div class="img"> <img src="Tomorrow.png" alt="Tomorrow" width="220"> <p id="answer8">Quelle est le mot?</p> </div> </center> <br> <br> <br> <br> <p>Date&#58;</p> <p id="date"></p> <script> var today = new Date() var day = today.getDay() + 1 var dd = today.getDate() var mm = today.getMonth() + 1 var yyyy = today.getFullYear() if (dd < 10) { dd = '0' + dd } if (mm < 10) { mm = '0' + mm } if (mm = 01) { mm = 'janvier' } if (mm = 02) { mm = 'février' } if (mm = 03) { mm = 'mars' } if (mm = 04) { mm = 'avril' } if (mm = 05) { mm = 'mai' } if (mm = 06) { mm = 'juin' } if (mm = 07) { mm = 'juillet' } if (mm = 08) { mm = 'août' } if (mm = 09) { mm = 'septembre' } if (mm = 10) { mm = 'octobre' } if (mm = 11) { mm = 'novembre' } if (mm = 12) { mm = 'décembre' } if (day = 1) { day = 'dimanche' } if (day = 2) { day = 'landi' } if (day = 3) { day = 'mardi' } if (day = 4) { day = 'mercredi' } if (day = 5) { day = 'jeudi' } if (day = 6) { day = 'vendridi' } if (day = 7) { day = 'samedi' } if (dd = 01) { dd = 'premier' } if (dd = 02) { dd = 'deux' } if (dd = 03) { dd = 'trois' } if (dd = 04) { dd = 'quatre' } if (dd = 05) { dd = 'cinq' } if (dd = 06) { dd = 'six' } if (dd = 07) { dd = 'sept' } if (dd = 08) { dd = 'huit' } if (dd = 09) { dd = 'neuf' } if (dd = 10) { dd = 'dix' } if (dd = 11) { dd = 'onze' } if (dd = 12) { dd = 'douze' } if (dd = 13) { dd = 'treize' } if (dd = 14) { dd = 'quatorze' } if (dd = 15) { dd = 'quinze' } if (dd = 16) { dd = 'seize' } if (dd = 17) { dd = 'dix&ndash;sept' } if (dd = 18) { dd = 'dix&ndash;huit' } if (dd = 19) { dd = 'dix&ndash;neuf' } if (dd = 20) { dd = 'vingt' } if (dd = 21) { dd = 'vingt&ndash;et&ndash;un' } if (dd = 22) { dd = 'vingt&ndash;deux' } if (dd = 23) { dd = 'vingt&ndash;trois' } if (dd = 24) { dd = 'vingt&ndash;quatre' } if (dd = 25) { dd = 'vingt&ndash;cinq' } if (dd = 26) { dd = 'vingt&ndash;six' } if (dd = 27) { dd = 'vingt&ndash;sept' } if (dd = 28) { dd = 'vingt&ndash;huit' } if (dd = 29) { dd = 'vignt&ndash;neuf' } if (dd = 30) { dd = 'trente' } if (dd = 31) { dd = 'trente&ndash;et&ndash;un' } document.getElementById("date").innerHTML = today = 'Aujourd&#8217;hui c&#8217;est ' + day + '&#44; le ' + dd + ' ' + mm + '&#44;' + yyyy; </script> </head> <body style="filter:progid:DXImageTransform.Microsoft.Gradient(endColorstr='#FF6666', startColorstr='#FFFFFF', gradientType='0');"> </body> </html>

In Javascript you have to do comparison with "==" or "==="

Your current if statements contain "=" which would be doing assignment and not comparison. 

  <script>
    var today = new Date()
    var day = today.getDay() + 1
    var dd = today.getDate()
    var mm = today.getMonth() + 1
    var yyyy = today.getFullYear()


    if (dd < 10) {
      dd = '0' + dd
    }

    if (mm < 10) {
      mm = '0' + mm
    }

    if (mm == 01) {
      mm = 'janvier'
    }
    if (mm == 02) {
      mm = 'février'
    }
    if (mm == 03) {
      mm = 'mars'
    }
    if (mm == 04) {
      mm = 'avril'
    }
    if (mm == 05) {
      mm = 'mai'
    }
    if (mm == 06) {
      mm = 'juin'
    }
    if (mm == 07) {
      mm = 'juillet'
    }
    if (mm == 08) {
      mm = 'août'
    }
    if (mm == 09) {
      mm = 'septembre'
    }
    if (mm == 10) {
      mm = 'octobre'
    }
    if (mm == 11) {
      mm = 'novembre'
    }
    if (mm == 12) {
      mm = 'décembre'
    }

    if (day == 1) {
      day = 'dimanche'
    }
    if (day == 2) {
      day = 'landi'
    }
    if (day == 3) {
      day = 'mardi'
    }
    if (day == 4) {
      day = 'mercredi'
