TypeScript - create date object
In this article, we would like to show you how to create date object in TypeScript.
Quick solution:
xxxxxxxxxxnew Date() // gets current datenew Date(dateString) // dateString - String in a proper formatnew Date(milliseconds) // milliseconds - Unix time * 1000new Date(year, month, day, hours, minutes, seconds, milliseconds)
In this example, we use Date() constructor without any arguments to create a Date object initialized with the current datetime. Then we display the current datetime in ISO format.
xxxxxxxxxxconst date: Date = new Date();console.log(date.toISOString());Example output:
xxxxxxxxxx2022-03-22T14:03:02.393ZIn this example, we use Date() constructor with one argument to create the date object from a date string in a proper format. Then we display the date in ISO format.
xxxxxxxxxxconst dateString: string = '2021-09-07T15:55:00.000Z'; // String in a proper formatconst date: Date = new Date(dateString);console.log(date.toISOString());Output:
xxxxxxxxxx2021-09-07T15:55:00.000ZIn this example, we use Date() constructor with one argument to create the date object from unix time. To do so, we need to convert timestamp to milliseconds by multiplying it by 1000. Then we display the date in ISO format.
xxxxxxxxxxconst timestamp: number = 1630564245; // unix timestamp in secondsconst date: Date = new Date(timestamp * 1000);console.log(date.toISOString());Output:
xxxxxxxxxx2021-09-02T06:30:45.000ZIn this example, we use Date() constructor with many arguments to create the date object from specified data. Then we display the date in ISO format.
Syntax:
xxxxxxxxxxnew Date(year, monthIndex, day, hours, minutes, seconds, milliseconds)Practical example:
xxxxxxxxxxconst year: number = 2021;const monthIndex: number = 9; // 0-January, 1-February... 11-Decemberconst day: number = 7;const hours: number = 15;const minutes: number = 0;const seconds: number = 0;const milliseconds: number = 0;const date: Date = new Date(year, monthIndex, day, hours, minutes, seconds, milliseconds);console.log(date.toISOString());Output:
xxxxxxxxxx2021-10-07T13:00:00.000ZNote:
The hour in ISO format may be different depending on the time zone you live in. My time is currently given in GMT+0200 (Central European Summer Time), that's why ISO format subtracts 2 hours (from
15to13).
