The countdown block is part of Airtable Blocks, a Pro plan feature. Blocks let you extend the functionality of your bases: you can use blocks to bring new information into Airtable, visualize and summarize your records in colorful ways, and even directly integrate your Airtable bases with your favorite apps.
The countdown block shows a big countdown clock in the color and units of your choosing. You can set it to count down to a specific date and time, or to the earliest or latest date in a specific view.
When you first add a countdown block to your base, it'll automatically open the new block's settings page. There are two ways for you to set a date for the countdown block: you can set the countdown block to count down to a specific date, or you can it to count down to a date from a view.
If you want the block to count down to a specific date, simply click on the date/time picker and select the desired date and time, or type in your desired date and time.
If you want the block to count down to a date from a view, click the Date from view option, then specify a table, view, and date field. You can choose whether you want the block to count down to the earliest date in a view or the latest date in a view.
If you choose to count down to a date from a view, the countdown will change if the earliest or latest record in the view changes. For example, you can create a filtered view which shows all records with deadlines after today, and set the countdown block to count down to the earliest date in that view. As deadlines pass and records leave the view, the countdown block will change to match the new earliest dates in the view.
You can customize the countdown's time units—from years and months down to minutes and seconds—by checking and unchecking the appropriate boxes in the Units section. You can also adjust the color of the countdown numbers.
