Notes:

1. Notice that 2020/05/05 is today's date (or is about to be).
2. Enter that date as one whole number on a calculator (one that uses 7-segment displays, that is) in either YYYYMMDD, YYYYDDMM, MMDDYYYY, or DDMMYYYY format. An examples of such a calculator include virtually all four-function calculators and those in the TI-30 series. (It doesn't actually have to be a calculator, just a device that can show an 8-digit number using a 7-segment display which you can manipulate to show the date as a whole number.)
3. Take a photo of the number as it appears on the display.
4. Flip the photo horizontally.
5. ???
6. PROFIT!
7. Wait ever-so-slightly less than 3030 years to do similar steps again!

Posted early for those west of the IDL where it is well into May 5. Good afternoon-bordering-on-evening, Republic of Kiribati!

(I learned a lot about image editing making this one!)
