If you want to be able to set an alarm for a future date on your iPhone, there are a few different ways that you can go about it. The first way is to use the built-in Calendar app. To do this, open the Calendar app and tap on the month that you want to set the alarm for. Then, tap on the date that you want to set the alarm for. Finally, tap on the “Alarm” button in the bottom right corner of the screen. The second way is to use an external calendar application. To do this, open up your favorite calendar application and find the month that you want to set the alarm for. Then, find the day that you want to set the alarm for and tap on it. Finally, tap on “Set Alarm” in the bottom right corner of the screen. The final way is to use Siri voice commands. To do this, press and hold down on one of your Home buttons until Siri pops up.
