# Working with Dates and Times

Airkit stores data regarding dates and times in specialized data types: the objects [Date](../../variable-data-types/the-date-variable-data-type), [Time](../../variable-data-types/the-time-variable-data-type), and [DateTime](../../variable-data-types/the-datetime-variable-data-type). Using these specialized objects in tandem with the Airkit platform allows Airkit to handle the notorious complexities of time-tracking under the hood.

## Dates

A `Date` object represents a particular calendar day. It consists of three properties:

* **day** (`number`) - the day of a month, where indexing begins at 1 with January
* **month** (`number`) - the month of a year, where 1 represents January, whereas 12 represents December
* **year** (`number`) - a year

For example, a `Date` representing June 16, 2022 would be given as:

```javascript
{
  "day": 16,
  "month": 6,
  "year": 2022
}
```

### Basic Applications

For the sake of example, assume all the following Airscript expressions have access to the following `Date`, `example_date`, which represents December 30th, 2021:

```javascript
example_date = {
  "day": 30,
  "month": 12,
  "year": 2021
}
```

On the surface, `example_date` behaves like any other object, the properties of which are accessible via dot notation. For instance, the value of the "day" property is accessible as follows:

```javascript
example_date.day ->  30
```

However, the true power of `Date` objects is in using them in tandem with parts of the Airkit platform that expect not just any object, but the special data type, `Date`.

`Date` values can used to generate `strings` that represent the described date in a more intuitive manner. The following example uses the [FORMAT\_DATE](../../airscript-expressions/datetime-functions/format_date) function to generate "December 30th, 2021" from `example_date`:

```javascript
FORMAT_DATE(example_date, "MMMM Do, YYYY") ->  "December 30th, 2021"
```

`Date` values can be modified such that they automatically account for calendar configuration. For instance, if [ADD\_TO\_DATE](../../airscript-expressions/datetime-functions/add_to_date) is used to add two days to `example_date`, this doesn't simply add 2 to the `day` attribute, it changes the `month` and `year` attributes to reference an appropriate date:

```javascript
ADD_TO_DATE(example_date, 2, "days") -> {
  "day": 1,
  "month": 1,
  "year": 2022
}
```

## Times

A `Time` object represents a time of day. It consists of four properties:

* **hour** (`number`) - an hour of a day represented by a 24-hour clock
* **minute** (`number`) - the number of minutes into the hour
* **second** (`number`) - the number of seconds into the minute
* \*\* millisecond\*\* (`number`) - the number of milliseconds into the second

For example, a `Time` representing 3:11 pm and 34 seconds would be given as:

```javascript
{
  "hour": 15,
  "minute": 11,
  "second": 34,
  "millisecond": 0
}
```

### Basic Applications

For the sake of example, assume all the following Airscript expressions have access to the following `Time`, `example_time`, which represents 11:15 pm and 30 seconds:

```javascript
example_time = {
  "hour": 23,
  "minute": 15,
  "second": 30,
  "millisecond": 0
}
```

On the surface, `example_time` behaves like any other object, the properties of which are accessible via dot notation. For instance, the value of the "hour" property is accessible as follows:

```javascript
example_time.hour ->  23
```

However, the true power of `Time` objects is in using them in tandem with parts of the Airkit platform that expect not just any object, but the special data type, `Time`.

For instance, `Time` values can used to generate `strings` that represent the described date in a more intuitive manner. The following example uses the [FORMAT\_TIME](../../airscript-expressions/datetime-functions/format_time) function to generate "11:15 pm" from `example_time`:

```javascript
FORMAT_TIME(example_time, "h:mm a") ->  "11:15 pm"
```

## DateTimes

A `DateTime` object represents a single moment in time: a certain time on a certain date. It can serve the same functions as a timestamp.

A `DateTime` object consists of three properties:

* **date** (`Date`) - a Date object, consisting of "day", "month", and "year" properties
* **time** (`Time`) - a Time object, consisting of "hour", "minute", "second", and "millisecond" properties
* **timeZone** (`string`, _timezone abbreviation_) - the timezone to which the date and time properties refer, tends to default to "UTC".

For example, a `DateTime` representing June 21, 2022, 9:34am and 48 seconds in UTC would be given as:

```javascript
{
  "date": {
    "day": 21,
    "month": 6,
    "year": 2022
  },
  "time": {
    "hour": 9,
    "minute": 34,
    "second": 48,
    "millisecond": 0
  },
  "timeZone": "UTC"
}
```

### Basic Applications

For the sake of example, assume all the following Airscript expressions have access to the following `Date`, `example_datetime`, which represents June 21, 2022, 9:34am and 48 seconds in UTC:

```javascript
example_datetime = {
  "date": {
    "day": 21,
    "month": 6,
    "year": 2022
  },
  "time": {
    "hour": 9,
    "minute": 34,
    "second": 48,
    "millisecond": 0
  },
  "timeZone": "UTC"
}
```

On the surface, `example_datetime` behaves like any other object, the properties of which are accessible via dot notation. For instance, the value of the "hour" property nested under the "time" property is accessible as follows:

```javascript
example_datetime.time.hour ->  9
```

However, the true power of `DateTime` objects is in using them in tandem with parts of the Airkit platform that expect not just any object, but the special data type, `DateTime`.

`DateTime` values can used to generate `strings` that represent the described moment in time in a more intuitive manner. The following example uses the [FORMAT\_DATETIME](../../airscript-expressions/datetime-functions/format_datetime) function to generate "06/21/22 9:34 AM UTC" from `example_datetime`:

```javascript
FORMAT_DATETIME(example_datetime, "MM/DD/YY h:mm A z") ->  "06/21/22 9:34 AM UTC"
```

`DateTime` objects can also be converted into strings that display the described moment in time in a more relevant timezone. The following example takes `example_datetime` and returns the described date and time not in UTC, but CDT:

```javascript
FORMAT_DATETIME(
  example_datetime,
  "MM/DD/YY h:mm A z",
  "en-EN",
  "America/Chicago"
) -> "06/21/22 4:34 AM CDT"
```

Note how the time changes to reflected the changes in timezone. **`DateTime` objects are a special time of object, capable of handling the complexities of timezone changes under the hood.**

This allows `DateTime` objects to serve the same functions as timestamps. In fact, a `DateTime` can be easily converted into a timestamp by giving it as input to the function [TIMESTAMP\_FROM\_DATETIME](../../airscript-expressions/datetime-functions/timestamp_from_datetime) – no other input required:

```javascript
TIMESTAMP_FROM_DATETIME(example_datetime) -> 1655804088000
```

Similarly, the [DATETIME\_FROM\_TIMESTAMP](../../airscript-expressions/datetime-functions/datetime_from_timestamp) function can be used to convert a timestamp to a `DateTime`, which allows timestamps collected by external systems to be used in Airkit apps.

### Timers

[Timers](https://docs.airkit.ai/?q=the-create-timer-action) can be used to schedule Actions to take place at some future time. The **Execution Time** can be defined as a **Custom Expression**, which expects a `DateTime` object as input.

To define a `DateTime` in relation to the current instant in time, you can use the [NOW](../../airscript-expressions/datetime-functions/now) function in tandem with the [ADD\_TO\_DATETIME](../../airscript-expressions/datetime-functions/add_to_datetime) function. The NOW function returns the `DateTime` at the instant it was called, and ADD\_TO\_DATETIME returns a `DateTime` at some specified instant after the given `DateTime`. For instance, the following example will return a `DateTime` specifying an instant in time five minutes from when the expression is called:

```javascript
ADD_TO_DATETIME(NOW(), 5, "minute")
```

Timers can also be set in relation to a future instant in time. For instance, say you've save the time of a future appointment to a `DateTime` variable called `appointment_time`. To set a Timer for one hour before the appointment – perhaps to send a reminder [Notification](../../sms/sms-notification-basics) – you can use the `appointment_time` variable in tandem with the [SUBTRACT\_FROM\_DATETIME](../../airscript-expressions/datetime-functions/subtract_from_datetime) function, as follows:

```javascript
SUBTRACT_FROM_DATETIME(appointment_time, 1, "hour")
```

### Scheduling

[Scheduler](../../web-controls/scheduler-web-control) Web Controls allow users to select appointment slots. They automatically save both the start and end time of the appointments as `DateTime` objects.

When stored as local variables, these start and end `DateTime` values can be used like any other `DateTime` object to, for instance:

* Set a [Timer](https://docs.airkit.ai/?q=the-create-timer-action) to issue a reminder [SMS Notification](../../sms/sms-notification-basics) a short time before the appointment.
* Confirm the appointment time in a [Label](../../web-controls/label-web-control) by using it as input in [FORMAT\_DATETIME](../../airscript-expressions/datetime-functions/format_datetime).
* Use a [Timer](https://docs.airkit.ai/?q=the-create-timer-action) to schedule a follow-up [Email Notification](../../emails/email-notification-basics) once the appointment is finished.

## Time Unit Values

There are many [Airscript]() functions that require [string](../../variable-data-types/the-text-variable-data-type) input designating a unit of time. In order to be correctly parsed by the Airscript function, the given string must exactly match one of the possible values given in the following table:&#x20;

| Time Unit   | Possible Values                     |
| ----------- | ----------------------------------- |
| Year        | "year", "years", "y"                |
| Month       | "month", "months", "M"              |
| Week        | "week", "weeks", "w"                |
| Day         | "day", "days", "d"                  |
| Hour        | "hour", "hours", "h"                |
| Minute      | "minute", "minutes", "m"            |
| Second      | "second", "seconds", "s"            |
| Millisecond | "millisecond", "milliseconds", "ms" |

## Date and Time Formatting Options

There are many [Airscript]() functions that require [string](../../variable-data-types/the-text-variable-data-type) input designating how a unit of time will be formatted. This by combining the tokens given in the following table:

| Unit                       | Token              | Output                                      |
