+# Instructions
+
+In this exercise you will code some functions in order to manage appointments.
+
+## 1. Create an appointment
+
+Create an appointment `x` days from now at current time.
+The function takes `x` as parameter and return the appointment time of `x` days from now.
+
+```javascript
+createAppointment(4);
+// If current time is 2022-10-01T12:50:13.000Z then the function will return  2022-10-05T12:50:13.000Z
+```
+
+## 2. Get details of an appointment
+
+The function takes an appointment time as argument and return a string containing information like below.
+
+```javascript
+getAppointment('24 April 2022 10:15 AM');
+// => { year: 2022, month: 3, date: 24, hour: 10, minute: 15 }
+```
+
+## 3. Update an appointment with given options
+
+The function will receive first argument as appointment time and second argument of object of some options.
+You have to update the appointment according to the options in the object and return the new appointment date.
+The options object could have multiple options.
+
+```javascript
+updateAppointment('09 February 2022 10:20 am', { month: 6 });
+// => { year: 2022, month: 6, date: 9, hour: 10, minute: 20 }
+```
+
+## 4. Get available times between two appointment
+
+The function will receive two appointment times as parameter.
+You have to return the difference between those two times in `ms`.
+
+```javascript
+availableTimes('12 December 2022 10:20 am', '18 December 2022 9:30 am');
+// => 515400000
+```
+
+## 5. Check if an appointment is now valid or not
+
+The function receives two arguments - appointment time and current time.
+If the appointment time is greater than the current time then the appointment is not valid anymore, and you should return `The appointment is not valid anymore.`
+If not, the appointment is valid, and you should return `The appointment is valid.`
+
+```javascript
+isValid('12 February 2022', '9 February 2022');
+// => The appointment is not valid anymore.
+```

+- `Date.now()` gives you current timestamp.
+- A day consist of 24 hour. An hour consist of 60 minutes. A minute consist of 60 seconds. A second consist of 1000 milliseconds. In order to get timestamp of `n` days later from current date, you can sum current timestamp and `n * 24 * 60 * 60 * 1000`.
+
+## 2. Get details of an appointment
+
+- Date object has [built-in methods][mdn-date-methods] to get different parts of the date.
+
+## 3. Update an appointment with given options
+
+- Date object has [built-in methods][mdn-date-methods] to modify date.
+
+## 4. Get available times between two appointment
+
+- General subtraction between two dates will give you the timestamp between the two dates.
+
+## 5. Check if an appointment is now valid or not
+
+- Conditional operators will help you to decide which date is bigger or smaller between two dates.

+# Introduction
+
+JavaScript has a built-in object `Date` which stores date and time, and provides methods for their management.
+
+## Creation
+
+A `Date` object in an instance of the `Date` class. It can be created without passing any arguments to the constructor function. This results in a `Date` object that represents the current date and time:
+
+```javascript
+const now = new Date();
+// => Thu Apr 14 2022 11:46:08 GMT+0530 (India Standard Time)
+
+// Shows current day, date and time in your time zone.
+```
+
+However, different types of arguments can also be used to create date object, as follows:
+
+### Timestamp value
+
+> A timestamp is an integer number representing the number of **milliseconds** that has passed since **Jan 1st of 1970 [UTC][utc-defn]+0**, however, _with reference to your local time zone._
+> This can be used as an argument for the Date object.
+>
+> ```javascript
+> const Jan01_1970 = new Date(0);
+> // 0 means 01.01.1970 UTC+0
+>
+> const Jan02_1970 = new Date(24 * 3600 * 1000);
+> // adding 24 hours, we get 02.01.1970 UTC+0
+>
+> // Note that the objects created here would show the corresponding time in your time zone.
+> ```
+>
+> [^1]
+
+### Timestamp string
+
+You can pass a string value representing a date to the `Date` constructor.
+The string needs to follow a format that is recognized by the `Date.parse()` method.
+You will learn more about this below.
+
+### Date object
+
+An existing date object can also be used as an argument.
+This makes a copy of the existing `Date` object with the same date and time.
+
+```javascript
+const t1 = new Date();
+const t2 = new Date(t1);
+
+// Values of t1 and t2 will be the same.
+```
+
+### Individual date and time component values
+
+> Given at least a year and month, this form of `Date()` returns a `Date` object whose component values _(year, month, day, hour, minute, second, and millisecond)_ all come from the following parameters.
+> Any missing fields are given the lowest possible value (1 for day and 0 for every other component).
+> The parameter values are all evaluated against the _local time zone, rather than UTC_.
+>
+> - `year`: Integer values from 0 to 99 map to the years 1900 to 1999.
+>   All other values are the actual year.
+> - `monthIndex`: Integer value representing the month, beginning with _0 for January to 11 for December_.
+>   If a value greater than 11 is passed in, then those months will be added to the date.
+>   For example, new Date(1990, 12, 1) will return January 1st, 1991.
+> - `day` (Optional): Integer value representing the day of the month.
+>   The default is 1.
+> - `hours` (Optional): Integer value between 0 and 23 representing the hour of the day.
+>   Defaults to 0.
+> - `minutes` (Optional): Integer value representing the minute segment of a time.
+>   The default is 0 minutes past the hour.
+> - `seconds` (Optional): Integer value representing the second segment of a time.
+>   The default is 0 seconds past the minute.
+> - `milliseconds` (Optional): Integer value representing the millisecond segment of a time.
+>   The default is 0 milliseconds past the second.
+>
+> [^2]
+
+```javascript
+const date1 = new Date(95, 11, 17);
+// Creates Date for Dec 17 1995 00:00 if your local timezone is equivalent to UTC.
+
+const date2 = new Date(2013, 12, 5, 13, 24, 0);
+// Creates Date for Jan 5 2014 13:24 if your local timezone is equivalent to UTC.
+```
+
+## `Date.parse()`
+
+`Date.parse()` takes **string as a input and returns a timestamp** (number of milliseconds from 1 Jan 1970 UTC+0), provided the string is in the format YYYY-MM-DDTHH:mm:ss.sssZ, where:
+
+> - `YYYY-MM-DD` - is the date: year-month-day.
+> - `T` - The character "T" is used as the delimiter
+> - `HH:mm:ss.sss` - is the time: hours, minutes, seconds and milliseconds.
+> - `Z` - This _optional_ part denotes the time zone.
+>   If `Z` is present, the `Date` will be set to UTC.
+>   If `Z` is not present, it will be Local Time.
+>
+> If the format is invalid, `NaN` is returned. [^3]
+
+Shorter variants are also possible, like `YYYY-MM-DD` or `YYYY-MM` or even `YYYY`. However, note that these variants **set the `Date` to UTC**, even though `Z` not mentioned.
+To understand what exactly happens check out [this section][mdn-diff-assumed-timezone] of a MDN page.
+
+```exercism/caution
+The use of `Date.parse()` (and the timestamp string method which works similarly) is strongly discouraged due to browser differences and inconsistencies. [^4]
+```
+
+## Accessing `Date` components
+
+The following are the methods to access the year, month and so on from the Date object:
+
+> - `getFullYear()`- Get the year (4 digits)
+> - `getMonth()`- Get the month, from 0 to 11.
+> - `getDate()`- Get the day of month, from 1 to 31.
+> - `getHours()`, `getMinutes()`, `getSeconds()`, `getMilliseconds()`- Get the corresponding time components.
+> - `getDay()`- Get the day of week, from 0 (Sunday) to 6 (Saturday).
+> - `getTime()`- Get the number of milliseconds passed since 01.01.1970 UTC.
+>
+> [^5]
+
+```javascript
+const date0 = new Date(0); //Jan 1 1970 00:00:00
+let month = date0.getMonth()); // => 0; as Jan is the month
+let date = date0.getDay(); // Find out which day the new year of 1970 was!
+
+const date1 = new Date(2020, 11, 13, 5); // Dec 13 2020 5:00:00
+let millsecs = date1.getTime(); // find out how many have milliseconds passed since Jan 1 1890!
+```
+
+## Modifying `Date` components
+
+The following methods allow to modify date/time components :
+
+> - `setFullYear(year, [month], [date])`
+> - `setMonth(month, [date])`
+> - `setDate(date)`
+> - `setHours(hour, [min], [sec], [ms])`
+> - `setMinutes(min, [sec], [ms])`
+> - `setSeconds(sec, [ms])`
+> - `setMilliseconds(ms)`
+> - `setTime(timestamp)` (sets the whole date by milliseconds since 01.01.1970 UTC)
+>
+> Parameters in `[]` above are _optional_.
+> If not mentioned, the components are not modified.
+> Every one of them except `setTime()` has a UTC-variant, for instance: `setUTCHours()`. [^6]
+
+```javascript
+let today = new Date();
+
+today.setHours(0); // still today, but only the hour is changed to 0
+
+today.setHours(0, 0, 0, 0); // still today, now sharply 00:00:00
+```
+
+## Calculating Time Difference and `Date.now()`
+
+To measure the time elapsed between two given dates, we can use the `Date.getTime()` method.
+
+```javascript
+const d1 = new Date(2021, 12, 11, 5, 13, 32, 21);
+const d2 = new Date(2021, 12, 23, 4, 12, 55);
+
+let timeElapsed = d2.getTime() - d1.getTime(); // => 1033162979
+```
+
+Moreover, if we wish to measure the time taken on a live basis, for example the time taken for execution for program, we could use `Date.now()` which provides the timestamp of current time.
+
+## Comparing Dates
+
+We can use `<` and `>` operators to compare two `Date` objects, the date occuring _later being treated as greater_.
+
+The `==` or `===` do not work with `Date`, and output `false` in any case, even if dates are equal.
+However, we could use the `Date.getTime()` method to obtain the timestamps (which is of the data type `number`) and compare them using equality operators.
+
+```javascript
+const d1 = new Date(2021, 12, 11);
+const d2 = new Date(1990, 11, 23);
+
+d1 > d2; // true
+
+const d1Copy = new Date(d1); // d1Copy will be same as d1
+
+d1Copy === d1; // false, even though they are same
+d1Copy.getTime() === d1.getTime(); //true
+```
