Calendar Sheet


Calendar buttons are found in the Prescription window and elsewhere.

Clicking calendar buttons opens the calendar dialog sheet. This is a modal dialog sheet which blocks its parent window until you exit the sheet.

The Calendar Sheet provides an alternative method of setting dates and times in addition to the MacOS conventional textual date picker controls found in the Prescription and a few other windows.

Standard MacOS controls are presented in this sheet and are supplemented with graphical elements as well. The left and right arrow bumper buttons above the calendar select the prior or subsequent month. The Today button copies the current date and time from your computer's system clock. To change the year you can repeatedly click the monthly arrow bumpers or enter the desired year directly in the textual date picker control under the clock.

To select a day, click on that day in the calendar or use the textual date picker. The calendar also responds to keyboard arrow keypresses when it has the user focus.

To enter a time of day, you can use either the textual date picker or simply click on the clock face's hourly labels to set the time to the nearest hour. Clicking on the same clock hour a second time exchanges AM and PM.

The Morning shortcuts are convenience controls that can accelerate selecting times between 7 AM and 2PM. For example, to select 7:35 AM, you can use your keyboard to enter "7" and "35" in the textual date picker under the clock, or alternatively click the 7:00 shortcut button followed by the +0:30 button followed by the +0:05 button.

Click OK to accept the currently displayed calendar sheet settings and exit the dialog.


The calendar sheet itself offers a graphical overview of the treatment at a glance. Treatment days are highlighted with a pale green (symbolizing "good to go") tint and a small plaque icon. The removal day icon has a white interior. The horizontal location of the plaque icon within a date box indicates the approximate time of day for insertion and removal. For a full day of treatment the icon is horizontally centered. Impossible treatment days (e.g. removal date set prior to implant date), and days that fall outside of your implant duration preference settings (e.g. too few or too many hours) are highlighted with a red warning tint. The background tint for March 11th in the example above features two colors, half green to indicate it is a treatment day and half grey with a thicker grey border to indicate that the 11th is the currently selected removal date.

Some special dates for the USA are highlighted with red (federal holidays) or orange (daylight savings time transition) text. In the example above, The plaque is inserted at 7AM on March 4th, 2020 and removed at 7 AM on March 11th. Normally the duration of such a one week implant would be 168 hours, but in this rare instance it will only be 167 hours because of the Spring daylight savings clock shift midway through the implant on Sunday March 8th. You can enable or disable observance of daylight savings time for your specific locale in your MacOS system Language & Region and/or Date & Time preferences panes using the Set date and time automatically and Time Zone settings.
