vanilla-js-full-current-date.js

// Formatted in D MMMM YYYY
// Eg; 18 October 2022
`${(new Date().getDate())} ${(new Date().toLocaleString("en", { month: "long" }))} ${(new Date().getFullYear())}`

// Formatted in D{ordinal} MMMM YYYY
// Eg; 18th October 2022
`${(new Date().getDate())}${{one:'st',two:'nd',few:'rd',other:'th'}[new Intl.PluralRules('en-GB', { type: 'ordinal' }).select(new Date().getDate())]} ${(new Date().toLocaleString("en", { month: "long" }))} ${(new Date().getFullYear())}`

// Formatted in DD-MM-YYYY
// Eg; 18-09-2022
`${String(new Date().getDate()).padStart(2,0)}-${String(new Date().getMonth()+1).padStart(2,0)}-${(new Date().getFullYear())}`

// Formatted {Day of week}
// Eg; Tuesday
`(new Date()).toLocaleString("en", { weekday: "long" })`

// **

// Subtract X-days from current date, then output
var d = new Date(); d.setDate(d.getDate()-5);

// ... Followed by your desired output, replacing `new Date()` with `d`. Eg;
`${String(d.getDate()).padStart(2,0)}-${String(d.getMonth()+1).padStart(2,0)}-${(d.getFullYear())}`
