如何在Slack重复提醒中显示对应日期而非占位符

Hey there, I’ve run into exactly this issue before—Slack’s native /remind command doesn’t natively support replacing placeholders like dd/mm/yyyy with the actual date when the reminder fires. But don’t worry, there are two solid workarounds to get this done:

1. Use Slack Workflow Builder (No Code Needed, Official Solution) #

This is the easiest and most reliable method since it’s built right into Slack:

• Open your Slack workspace, click your workspace name in the top-left corner > Tools > Workflow Builder
• Start a new workflow, select Scheduled date and time as the trigger. Set it to run every Tuesday at 07:00 AM.
• Add a Send message action. Choose yourself (or a channel) as the recipient.
• In the message input box, use Slack’s built-in date variable to pull the current date in your desired format:

  Today is {{date.now("DD/MM/YYYY")}}
  

  Slack will automatically replace this variable with the actual date when the workflow runs.
• Save your workflow and toggle it on—you’re all set!

2. Custom Script with Slack API (For Developers) #

If you’re comfortable with a bit of coding, you can use a script (like Google Apps Script or a Node.js script) to send dynamic reminders:

• Write a script that triggers on your desired schedule (e.g., weekly Tuesday 7 AM using a cron job or Google Apps Script’s time-driven trigger)
• Use the Slack API’s chat.postMessage method to send a message. In the message text, generate the current date formatted as dd/mm/yyyy using your script’s date functions (e.g., new Date().toLocaleDateString('en-GB') in JavaScript for dd/mm/yyyy)
• Authenticate the script with your Slack workspace’s API token, and you’ll get dynamic date reminders without relying on Slack’s native tools.

Quick Note on Why the Native /remind Command Fails #

Slack’s /remind treats the message content as static text—any placeholders you put in the quoted string won’t be parsed or replaced when the reminder is sent. That’s why dd/mm/yyyy shows up exactly as written instead of the actual date.
