## How Do Airtable Formulas Work?

At its core, an Airtable formula is simply a field type. When you are working in an Airtable base, you can select the formula field type from the available options in the table. To write a formula, you can choose from pre-existing functions or create your own. The formula will yield an output of a date, number, or string, and you can adjust the formatting preferences to display the output as desired.

Airtable formulas are applied to an entire column, rather than a single cell, allowing you to include information from other tables and resources within Airtable to enhance your formulas. This integration and flexibility make Airtable formulas a powerful tool for data management and analysis.

## Common Terminology in Airtable

Before diving deeper into Airtable formulas, it’s important to understand some common terminology used within the platform. This will help you navigate Airtable and effectively utilize formulas within your bases.

• Base: An Airtable base is equivalent to a workbook in Excel. It is a file that contains all of your tables and data.
• Table: Tables are Airtable’s equivalent of worksheets in Excel. They contain separate sets of data and can be linked to other tables.
• View: Views are different ways of organizing and viewing data within a table. They can be in the form of grids, calendars, galleries, and more.
• Field: Fields are equivalent to columns in Excel. They represent different types of data within a table.
• Record: Records are similar to rows in Excel. They contain individual sets of information stored within fields.
• Cell: Cells are individual data points within a table, just like in Excel.

## The Basics of Airtable Formulas

Formulas in Airtable are excallent when it comes to data manipulation. They allow you to go beyond the limitations of standard date and time fields and create custom fields tailored to your specific needs. With functions for numeric operations, logical operations, and text operations, the possibilities are endless.

To get started with formulas in Airtable, simply create a new field and select the formula type. From there, you can write formulas directly in the field’s text box and format them as needed. Don’t worry if you’re not a math genius – Airtable provides a range of pre-existing functions to use as a base for your formulas.

Now that we have a basic understanding of formulas and functions let’s dive into the date functions that will take your Airtable formulas to the next level.

### 1. Changing Your Date Format

One of the fundamental tasks in data manipulation is formatting dates correctly. Airtable provides the DATETIME_FORMAT() function to help you achieve this. This function allows you to specify the output format of your date, providing flexibility and control over how your dates are displayed.

To change the format of a date, simply use the following syntax:

DATETIME_FORMAT(<date>, '<output format>')

For example, if you want to display the current date in the format “YYYY-MM-DD,” you can use the following formula:

DATETIME_FORMAT(NOW(),'YYYY-MM-DD')

With the DATETIME_FORMAT() function, you can quickly generate date formats that suit your specific needs. Whether you’re working with international collaborators or need to include additional details in your dates, this function has got you covered.

### 2. Calculating the Duration of an Event

Another essential date calculation is determining the duration of an event. The DATETIME_DIFF () function in Airtable allows you to calculate the difference between two dates, giving you the precise duration of an event.

To use the DATETIME_DIFF() function, you need two existing date/time fields in your table and the desired units of measurement. The syntax is as follows:

DATETIME_DIFF(<date1>, <date2>, 'units')

For example, if you want to calculate the duration between a start date and today in days, you can use the following formula:

DATETIME_DIFF({Start date}, TODAY(), 'days')

This function is incredibly versatile and allows you to measure time durations in various units, including weeks, months, minutes, and hours. With the DATETIME_DIFF() function, you can easily keep track of the duration of your events and make informed decisions based on that information.

### 3. Automatically Adding to a Date

The DATEADD() function in Airtable is a powerful tool for adding a count to a date and time in your table. This function is particularly useful when you need to automate tasks that involve adding or subtracting time from a specific date.

To use the DATEADD() function, you need another date field in your table and a count and unit to add to that date. The syntax is as follows:

For example, if you want to subtract one month from a deadline date, you can use the following formula:

The DATEADD() function opens up a world of possibilities for automating tasks and keeping your data up to date. Whether you need to calculate project deadlines, schedule recurring events, or create countdowns, this function has got you covered.

### 4. Turning Text into a Legible Date

In some cases, you may need to convert a text field into a readable date format. The DATETIME_PARSE() function in Airtable allows you to do just that. This function is particularly useful when importing values from external sources or dealing with dates that are not initially recognized by Airtable.

To use the DATETIME_PARSE() function, you need to provide the text field, the input format of the text, and the locale if necessary. The syntax is as follows:

DATETIME_PARSE(date, <'input format'>, <'locale'>)

For example, if you have a text field with the value “4 Mar 2017 23:00” and want to convert it into a readable date format, you can use the following formula:

DATETIME_PARSE("4 Mar 2017 23:00", 'D MMM YYYY HH:mm')

The DATETIME_PARSE() function allows you to convert text fields into readable dates, making it easier to work with your data and perform calculations based on that information.

### 5. Setting up Recurring Yearly Events

If you frequently deal with recurring events, such as birthdays or anniversaries, the DATETIME_FORMAT()  and DATETIME_PARSE() functions can be used in combination to set up automated recurring events in Airtable.

First, select an existing date field and extract the month and day from it using the DATETIME_FORMAT() function. Then, combine the formatted month and day with the current year using the DATETIME_PARSE() function. This will ensure that the recurring events are updated to reflect the current year automatically.

Here’s an example formula to set up recurring yearly events:

DATETIME_PARSE(DATETIME_FORMAT({Date},'MM/DD') & "/" & YEAR(NOW()))

By leveraging these functions, you can save time and effort by automating the process of setting up recurring events in Airtable. Whether it’s birthdays, holidays, or any other annual events, you can ensure that the dates are always up to date without manual intervention.

### 6. Automatically Displaying and Updating Deadlines in Work Days

Deadlines are an essential aspect of project management, and having a countdown to a deadline can help keep everyone on track. TheWORKDAY_DIFF() function in Airtable allows you to calculate the number of working days left until a specific date, excluding weekends.

To calculate the number of working days left, simply use the following formula:

WORKDAY_DIFF(TODAY(), Date)

By default, the WORKDAY_DIFF() function includes both the start and end day in the total number of days. However, you can choose to exclude specific dates, such as bank holidays, by manually adding them to the formula.

For example, if you want to exclude the dates’ 2021-09-23′, ‘2022-01-21’, and ‘2022-08-19’ from the calculation, you can use the following formula:

WORKDAY_DIFF(TODAY(), Date, '2021-09-23, 2022-01-21, 2022-08-19')

The WORKDAY_DIFF() function is a valuable tool for project management, allowing you to display the number of working days left until a deadline and ensure that everyone is aware of the time constraints.

### 7. Automatically Populating Your Project with Due Dates

If you frequently work on projects with fixed timelines, you can automate the process of populating due dates in Airtable using the DATEADD() function. By establishing a set timeline for your projects, you can create fields for each step of the process and automatically populate them relative to the final due date.

For example, if your first draft is always due seven days before the final due date, you can use the following formula:

By leveraging the DATEADD() function, you can automate the process of setting due dates for each step of your project. This saves time and ensures that everyone is aware of their deadlines, improving collaboration and productivity.

### 8. Generating the Week, Month, or Quarter Number

To prioritize and organize your tasks effectively, you can use Airtable formulas to generate the week, month, or quarter number for a specific date. By breaking down dates into their respective positions in the year, you can group records, sort tasks, and gain valuable insights into your project timeline.

To generate the quarter number for a date, for example, you can use the following formula:

CONCATENATE("Q", DATETIME_FORMAT(Date, "Q YYYY"))

By swapping out “Q” with “W” or “DDD”, you can also generate the week number or day number, respectively. This allows you to customize the formatting according to your preferences and gain a deeper understanding of your project timeline.

### 9. Displaying Specific Messages Based on the Day of the Week

If you want to add a personalized touch to your Airtable projects, you can use the SWITCH()  and WEEKDAY() functions to display specific messages based on the day of the week. This is particularly useful if you’re using Airtable in combination with a website or app and want to provide dynamic content based on the current day.

To configure a specific message for each day of the week, you can use the following formula:

SWITCH(WEEKDAY({Date}),

0, ‘Sunday fun day!’,

1, '#MondayMotivation',
2, 'Have a good Tuesday!',
3, 'Happy Hump Day!',
4, '#TBT',
5, 'Thank God it's Friday',

By customizing the messages for each day, you can create a dynamic experience for your users and keep them engaged with your content.

### 10. Using IF Formulas Along With Date Fields

IF formulas are a powerful way to add conditional logic to your Airtable base. When combined with date fields, they can help you determine whether a given date is before, after, or the same as another date. This can be useful for displaying time-related messages or triggering specific actions based on the date.

The syntax of an IF formula is straightforward, with three arguments: the logical test, the value to return if the logical test is true, and the value to return if the logical test is false. For example, to determine if a date is today, you can use the following formula:

IF(IS_SAME(Date, TODAY(), 'days'), "It's today", "It's not today")

By leveraging IF formulas, you can add a layer of depth and personalization to your Airtable base, making it more interactive and responsive to changes in the date.

### 11. Setting Time Zones and Locales

As businesses increasingly work with collaborators across different time zones, it’s essential to ensure that your data is displayed accurately for each user. Airtable allows you to set time zones and locales on a per-field basis, ensuring that dates are presented correctly to everyone.

By default, Airtable stores data using Greenwich Mean Time (GMT). However, you can choose to use the same time zone for all collaborators or display dates based on each collaborator’s local time zone. To set a specific time zone for a field, you can use the SET_TIMEZONE() function, along with the desired time zone.

For example, to display a date in the ‘Europe/Oslo’ time zone, you can use the following formula:

SET_TIMEZONE({Appointment time}, 'Europe/Oslo')

This allows you to accommodate users in different time zones and ensure that they see the correct dates and times based on their location.

In addition to setting time zones, Airtable also allows you to set locales, which determine the formatting of dates and times based on a specific language or region. By combining the SET_LOCALE() function with the DATETIME_FORMAT() function, you can create a truly personalized experience for your users.
