The Niko Niko calendar is a tool used by some teams to track how happy or sad everyone feels each day. Instead of just noting down tasks or meetings, people also write down their moods. This helps the team see if there are any patterns in how people are feeling over time.

Each team member puts a colour (like in the example above) or a smiley like a happy face, sad face, or neutral face on the calendar to show their mood for the day. It’s a simple way for everyone to share how they’re doing without needing to have long discussions about it.
By using the Niko Niko calendar, teams can understand if there are any problems affecting people’s happiness and work together to fix them. It’s a way to keep track of the team’s emotional well-being alongside their work progress.
A retrospective would be a good place to review the Niko Niko of the last sprint and gain some insights, what events caused the different moods.
