February 30 was a real date in Sweden in 1712.
Instead of changing from the Julian calendar to the Gregorian calendar by omitting a block of consecutive days, as had been done in other countries, the Swedish Empire planned to change gradually by omitting all leap days from 1700 to 1740, inclusive. Although the leap day was omitted in February 1700, the Great Northern War began later that year, diverting the attention of the Swedes from their calendar so that they did not omit leap days on the next two occasions; 1704 and 1708 remained leap years.
To avoid confusion and further mistakes, the Julian calendar was restored in 1712 by adding an extra leap day, thus giving that year the only known actual use of February 30 in a calendar. That day corresponded to February 29 in the Julian calendar and to March 11 in the Gregorian calendar.
Although many sources erroneously state that 30-day months were used in the Soviet Union for part or all of the period from 1929 to 1940, the Soviet calendar with 5- and 6-day weeks was used only for assigning workdays and days of rest in factories. The Gregorian calendar (since 1918) remained for everyday use: surviving physical calendars from that period show only the irregular months of the Gregorian calendar, including a 28- or 29-day February, so there was never a February 30 in the Soviet Union.
Many congratulations!
For those who wanted an explanation of my little puzzle:
The date February 30 did appear on a real calendar, once in history. I'll let wikipedia explain the circumstances:
Some have suggested that the Soviet Union had a February 30 after the revolution, this appears not to be true. Again, wikipedia:
Thus, 1712 was the only year with a real February 30.
I do so hope it's a more approachable genre this time...though who knows, I may wind up not doing another one yet again, I've had tremendous block for the longest time now...

As soon as I saw the parameters for the challenge, the vision of Marilyn Monroe singing Happy Birthday was my inspiration. I knew I would build my story around seduction. The last line was meant innocently enough. It wasn’t until I read it over the second time that I appreciated the pun, and hoped others would as well.Meanwhile, as for favorites, the coded puzzle pieces seem to have gone over my head. I was drawn to sidewise references.
