Date

Constructors: 

new TDate(): TDate;
new TDate(year: number,  month: number, day: number): TDate;

alues of this type are immutable, so mutation methods return an updated value without modifying the original. 

const date = new TDate(2022, 2, 24);   // 2022-02-24 
const  newDate = date.addDate(0, 1, 5); // 2022-03-29

Note that the type TDate оdiffers from the built-in JavaScript type Date. This type contains only date information, without the time of day.
