What is a Niko-Niko Calendar?

A Niko-Niko Calendar is a straightforward yet effective visual tool used in Agile teams to track and understand team members’ emotions and overall morale over time. The name “Niko-Niko” comes from the Japanese word for smiling, which reflects the calendar’s purpose—to gauge emotional well-being.

In Agile projects, team dynamics and happiness are crucial for maintaining productivity and fostering collaboration. This calendar provides a transparent way to monitor these dynamics while encouraging open communication.

How Does a Niko-Niko Calendar Work?

Each day, team members indicate their mood on the calendar using simple symbols such as happy, neutral, or sad faces. These symbols are often color-coded for better visibility.

• 😊 Happy face: Represents a good day or positive mood.
• 😐 Neutral face: Indicates an average day or mixed feelings.
• 😞 Sad face: Reflects a tough day or negative emotions.

The team places these icons on a shared calendar, typically visible to everyone in a physical workspace or digital tool.

Over time, the calendar reveals patterns, helping the team or Scrum Master identify potential issues like stress, burnout, or lack of engagement.
