1st Post

<script>
var d= new Date();

let date= d.getDate()+"-"+d.getMonth()+1+"-"+d.getFullYear();
document.getElementById("your tag id").innerHTML= date;
firebase.database().ref('/user/'+ username).set({
//User table, Username Key
            Name:name,
            Email:email,
            Password:password,
            Phone:phone,
            DateofRegistration :date
        });
</script>

Date Function in Detail-
getMonth() - Returns months in range 0 to 11 ~So for correct month d.getMonth+1
getDate() - 0-31
getFullYear()
getHours()- 0-23
getMinutes() - 0-59
getSeconds() - 0-59

4 Methods for date object constructor-

new Date()

new Date(year, month, day, hours, minutes, seconds, milliseconds)

new Date(milliseconds)

new Date(date string)

I referred w3Schools for this topic.
