Hourly Activity Density

This heatmap shows the normal working rhythm of the team — the hours and days when Jira activity is concentrated. It establishes the baseline that makes off-hours anomalies visible. A team working 9-to-5 Monday to Friday will show a very different pattern from a globally distributed team, and both are valid.

Understanding the normal pattern is the prerequisite for identifying deviations from it.

What you can conclude

• A dense cluster in standard business hours for a single timezone indicates a co-located team with predictable working hours.
• Activity spread across all hours suggests a globally distributed team — off-hours anomaly detection needs to be calibrated to local time zones.
• A sudden change in the density pattern (previously quiet evenings becoming active) may indicate a team change, new automation, or unauthorized access.

How this chart works

Heatmap showing average event volume per hour of day (x-axis, UTC) × day of week (y-axis). Darker cells indicate higher average activity. Use the date and project filters to build the baseline for a specific team.
