# Date formats in JavaScript

Let's now learn how to display the date in a specific format. Let, for example, we want to display the current day, month and year in the format year-month-day.

Let's do that:

`let date = new Date(); console.log(date.getFullYear() + '-' + date.getMonth() + '-' + date.getDate());`

Our code, however, has a problem: the month numbers will start with a zero, and we would most likely want them to start with a one.

Let's fix the problem:

`let date = new Date(); console.log(date.getFullYear() + '-' + (date.getMonth() + 1) + '-' + date.getDate());`

Our code, however, is still not perfect. But you can notice this only in certain months and on certain days. Let, for example, it is now `5`th of March `2020`.

In this case, our date will be displayed in the format 2020-3-5. And we would like the date to be displayed in the format 2020-03-05 - with zeros before the numbers of days and months with one digit.

To solve the problem, let's write the function `addZero`, which will add zeros in front of numbers from `0` to `9`:

`function addZero(num) { if (num >= 0 && num <= 9) { return '0' + num; } else { return num; } }`

Let's apply the created function and now we will actually get the date in the format we need:

`let date = new Date(); console.log( addZero(date.getFullYear()) + '-' + addZero(date.getMonth() + 1) + '-' + addZero(date.getDate()) );`

Display the current date-time in the format 12:59:59 31.12.2014. Use for all parts of the date (except for the year) the function we created to add a zero if necessary.
