Daylight Saving Time Notification

This workflow is designed to automatically monitor and notify about upcoming changes to Daylight Saving Time, ensuring that cross-timezone teams can timely adjust their meeting schedules. It supports sending reminders via both Slack and email, reducing communication errors caused by time changes. Users can flexibly configure the monitored time zones, and the system will automatically determine and send reminders, enhancing the efficiency and accuracy of remote collaboration while minimizing the risk of human oversight.

Workflow Name

Daylight Saving Time Notification

Key Features and Highlights

This workflow automatically monitors whether preset time zones are about to enter or exit Daylight Saving Time (DST) and sends reminder notifications one day in advance. It supports notifications via both Slack messages and emails, helping teams adjust meeting schedules promptly and avoid communication errors caused by time changes.
Highlights include:

  • Automatic detection of DST status changes across multiple time zones
  • Flexible configuration of monitored time zone lists
  • Multi-channel notifications (Slack and email) to ensure message delivery
  • Integration with n8n’s scheduling trigger for regular automated monitoring

Core Problem Addressed

Teams operating across multiple time zones or businesses involving various regions often face meeting confusion or missed important events due to DST adjustments. This workflow solves the problem of automatically detecting DST changes in time zones and sending advance reminders, reducing the risk of human oversight and improving cross-time-zone collaboration efficiency.

Use Cases

  • Multinational companies managing meetings across different countries or regions
  • Daily coordination for remote and distributed teams
  • Project management requiring synchronization of multi-time-zone changes
  • Any service or system management relying on accurate time scheduling

Main Workflow Steps

  1. Scheduled Trigger: The workflow is initiated at regular intervals using the Schedule Trigger node.
  2. Load Time Zone List: The monitored time zones (e.g., New York, Warsaw) are set via a Code node.
  3. Calculate Current Time per Time Zone: Determine the current date and time for each time zone.
  4. Calculate Next Day Time: Compute the date and time for the following day in each time zone.
  5. Check for DST Change: Compare the DST status of the current day and the next day to detect any changes.
  6. Conditional Check: If a DST change is detected for the next day, proceed to send notifications.
  7. Send Notifications: Dispatch reminder messages to specified Slack channels and email lists via Slack and Email nodes respectively.

Involved Systems and Services

  • Slack: For sending instant message notifications; requires OAuth authentication configuration.
  • SMTP Email Service: For sending email alerts; requires SMTP account setup.
  • n8n Core Nodes: Including Manual Trigger (for manual testing), Schedule Trigger (for timed execution), Code node (for time zone list), Set node (for time calculations and checks), and If node (for conditional logic).

Target Users and Value

  • Cross-time-zone team managers and coordinators
  • Project managers requiring precise time synchronization
  • IT operations and automation engineers
  • Any enterprise users aiming to reduce time management errors through automation

By using this workflow, users can automatically and accurately receive notifications about DST changes, preventing communication and collaboration disruptions caused by time adjustments, thereby enhancing the smoothness and efficiency of cross-time-zone teamwork.
