Abstract: A method and system for day management using an integrated calendar is disclosed. A user inputs his time available during a period and enters details on time-specific events to be performed during that period. The system fetches information entered by user and stores the details in the integrated calendar. Tasks to be performed are stored on task list in order of priority as entered by the user. The system determines free time available with the user for performing the tasks by subtracting the time allocated for the events from the time available. Further, tasks are allocated time schedules by allocating that free time to the duration of each task, as per priority. If a task cannot be performed in a particular time slot within the time period, the task may be split into multiple smaller tasks and performed at different time slots that are available.
