The Countdown block displays the number of days, months, and years until a particular target date. The date is selected with an intuitive date picker and a title can be added above the countdown to provide additional context. Optionally, the number of minutes and hours can also be shown.
The block accepts targetDateTime [string] in ISO 8601 date and time format and uses the Graph Service's updateEntity method to store this in the embedding application's storage. title [string] and displayTime [boolean] properties set the title and hours and minutes options respectively.
