temporal-evaluation

To evaluate task urgency and overdue status, compare due dates against the current time using timezone-aware calculations. This labels tasks as overdue, urgent, upcoming, or soon to provide clear prioritization context.

The recommended time windows for classifying tasks are 6 hours for urgent, 24 hours for upcoming, and 1 week for soon. These fixed windows help standardize prioritization and trigger appropriate notifications.

Relative time displays and temporal statuses should be updated every 60 seconds. This fixed interval ensures dashboards and task lists remain accurate while continuously reflecting current overdue and urgent conditions.

When calculating task temporal status, missing due dates must be handled as specific edge cases. The evaluation logic safely skips overdue or urgent labeling for these tasks to prevent invalid timezone comparisons.

Timezone-aware scheduling ensures relative time displays accurately reflect each user's local time. Calculations compare the user's timezone with the task's due date to generate correct human-readable strings.

Continuous temporal evaluation should be applied when tasks are created, updated, or displayed in a dashboard. This ensures real-time overdue and urgent classifications remain accurate during the entire app session.
