How DATETIME_DIFF Works

The DATETIME_DIFF function calculates the difference between two points in time, returning the result in a unit of your choosing—be it days, hours, minutes, or seconds. This versatility makes it an essential tool for a wide range of applications within Airtable.

Basic Syntax

The basic syntax of the DATETIME_DIFF function is:

				
					


DATETIME_DIFF(Date1, Date2, 'units')

Date1 and Date2 represent the two dates or times you want to compare. Date1 is typically the later date, while Date2 is the earlier one.

'units' specifies the unit of time for the output. You can choose from 'seconds', 'minutes', 'hours', 'days', 'weeks', 'months', or 'years'.
				
			

Example Use Cases

  1. Project Deadline Tracking: Calculate the remaining days before a project deadline to prioritize tasks and manage team workload effectively.

  2. Event Planning: Determine the number of weeks or months until an upcoming event to stay on top of planning milestones and deadlines.

  3. Time Tracking: Measure the duration of activities in hours or minutes, useful for billing, productivity analysis, or time-sensitive processes.

Getting Started with DATETIME_DIFF
