Countdown

My first Python project. You give it a date (optionally with a time and an event name) and it tells you how long you have until it — and that's pretty much it. A few details I paid attention to:

• Attach a custom time and name to the event
• Reject 00:00 as a custom time
• Leave both the time and name fields optional
• Let the user confirm their inputs before locking them in
• Restart the program with a fresh date at the end
• Use different wording for dates in the past
