## Abstract

A method of dynamically adjusting a circadian rhythm comprising the steps of determining a current circadian rhythm status of a circadian rhythm of an observer, accessing a calendar of the observer, and identifying a future event of the observer to precondition for, defined as an identified future event. A preconditioning schedule responsive to the identified future event may then be determined. Furthermore, communication with a light source may be established, and the light source may then be operated to emit light according to the preconditioning schedule.

determining a current circadian rhythm status of a circadian rhythm of an observer;
accessing a calendar of the observer;
identifying a future event of the observer to precondition for, defined as an identified future event;

establishing communication with a light source; and
operating the light source to emit light of the preconditioning schedule.

### Claim 2 (depends on 1)

determining the time of day for the observer;
determining the time zone of the observer; and
determining the date.

### Claim 3 (depends on 1)

accessing future events within a timeframe from the calendar; and
determining which future events require preconditioning.

### Claim 4 (depends on 3)

### Claim 5 (depends on 4)

The method of claim 4 further comprising the steps of:
determining if the any of the preconditioning schedules for the multiple identified future events conflicts;
upon a determination that no conflict exists, performing the step of operating the light source to emit light of the preconditioning schedules; and
upon a determination that a conflict exists, performing the steps of:
querying a user to select one or more non-conflicting future events,
receiving an input from the user indicating one or more future events to precondition for, and
