Countdown Star is the best way to countdown to — and count up from — all of your favorite events.

Countdown to birthdays, holidays, an upcoming vacation, a wedding, the New Year, parties, sporting events, concerts and more.
Count up from anniversaries, the day you were born, and other special events in the past.

* How many seconds until your next birthday?
* How many months since you were born?
* How many days until you graduate from college?
* How many hours until your anniversary?
* How much time is left until your vacation starts?
* How many days until Christmas?
* How many minutes until your party begins?
* How much time is left until your baby's due date?

Countdown Star is the countdown app that lets you choose which events to add, then makes every one of them your own.

Features:

* Home Screen Widget — glance at your countdowns without opening the app, and resize it right on your home screen; the more room you give it, the more events it shows
* Celebration Animations — choose Confetti, Fireworks, Balloons, Stars, or Lasers when your countdown reaches zero
* Repeating Events — annual events automatically advance to the next year so you never have to update them
* Backup and Restore — your events and settings are backed up automatically, and you can export everything, including your own wallpapers, to a file you can restore on any device
* Home Event — pick the event Countdown Star opens to every time you launch it
* Add Your Own Events — add as many events as you like
* Custom Wallpapers — choose from 15 built-in wallpapers or use your own photos
* Time Zone Support — set each event in any time zone with localized city names
* Sort and Search — sort by date, title, or your own custom order; events are sectioned into Countdown and Count Up groups
* Favorites and Notifications — mark events as favorites to receive a notification when their countdown reaches zero
* Interactive Slider — instantly switch between seconds, minutes, hours, days, weeks, months, or years to see your countdown exactly how you want it
* Customizable Timer — choose the timer position, background style and digit weight, show or hide weeks, and toggle the leading zero
* Share — send an event's countdown to a friend, with or without a screenshot
