TypeScript - day name for specific Date

In this article, we would like to show you how to get the day name for a specific date in TypeScript.

Quick solution:

const DAY_NAMES: string[] = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];

const now: Date = new Date();
const day: string = DAY_NAMES[now.getDay()];

console.log(day);

Note: in the above example we need to provide day names by ourselves to keep legacy with older TypeScript versions.

Practical example

const DAY_NAMES: string[] = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];

const getDayName = (date: Date): string => {
  return DAY_NAMES[date.getDay()]; // day from 0 (Sunday) to 6 (Saturday)
};


// Usage example:

const now: Date = new Date();

console.log(getDayName(now));

Example output:

Thursday
