Feature description

Currently the alarms can be set to be rung on specific weekdays as needed. This could be further improved but adding the option to:

1. Have a alarm ring on specific dates selected by a user
2. Have the alarm ring every day from a start date to end date

Proposed possible implementations:

1. Have new options for date range and specific dates. Clicking on them will bring up a date selector similar to the Calendar app.
2. Have a pop-up menu to chose the type of occurrence and then show corresponding input options.

For 2:

• So, if a user selects once no option would be shown. If daily is selected, no other input option is shown. If specific weekdays is chosen then the current day chooser would be shown
• For the date range option: The start and end date will be shown. If tapped on, a date picker will pop-up. First click determines the start date and second click determines the end date. And the selected dates highlighted until the user presses "Ok"
• For specific dates: The chosen dates will be shown. Tapping on them shows the date selector with currently selected dates highlighted. User can click more dates (which will highlight them) and select more dates

Why do you want this feature?

This provides more versatality as the user can set alarms for specific days/range of days in the future. This is removes the requirement of needing to set an alarm right before
