This is "when" the time frame is configured. All types have an optional recurrence that can be configured, except for "always" (since there's nothing to recur if the time is always). Next to this column, there is also a summary of the choices selected here (this column is unlabeled

Time frame options are:

• Always: This is always / all the time; used as a catch-all for users without time frames
   
• Days of the Week: This is a weekly schedule for days of the week with optional start/end times of the day. A hidden "copy all" button appears when you hover over to the right of the green + button. Its function is to copy one day's values to all of the other days of the week to save time selecting the same times repeatedly. 

• Specific Dates: these are exact dates and times, with the option to create multiple specific dates; click on the blue + button to add a date, and then don't forget to click "save" when finished

• Holidays: Select from a list of local and international holidays with an optional choice to recur; holiday options are maintained and updated by Calendarific
• Custom: This selection can combine days of the week, specific dates, and holidays to suit any time frame. Each new date entry will display in its own row, even if multiple dates were added simultaneously.
   

This is when the configured recurrence ends. The choice was configured after selecting "recurrence", either by an additional dropdown right underneath, or when selecting a "custom" recurrence. An end to a recurrence means this time frame should happen every week until this date.
