Nylas has introduced a feature called Specific Time Availability in its Scheduler, allowing users to set one-time availability windows that override regular schedules and automatically expire after use. This feature accommodates various scheduling needs like offering meetings at manually chosen times, setting availability for specific dates, and temporarily changing standard hours without permanent alterations. Specific Time Availability can be configured through the Scheduler Editor UI or via the API, where users can define dates and time ranges that take precedence over standard availability. This addition is designed to help manage special events, seasonal schedules, or last-minute changes without affecting regular calendar settings, and it is available to all users of the Nylas Scheduler, requiring the latest version of the Scheduler Editor package to access.
