I keep this on my iPhone screen and make it a large app display that shows the next event on the display and it counts me down to the next big date. It’s esthetically pleasing with customizable colors and icons to make all the birthdays one set up, or make them each unique. It’s up to you. You can set multiple reminders so you know when to shop, ship and the day of. I love not having to specifically load my calendar to see these important dates.
