Today we're going to party like it's 1999! (...or 1993 ...or 1982)
A Star Wars 'collectible' with little collectible value is usually just something that takes up space. If that expired collectible can have it's usefulness or function restored though, just having a purpose again will will also restore some of it's collectible value.|
The problem with calendars is that with the starting day of the year having seven different possibilities (Monday through Friday) multiplied by four for the snag leap year throws into the equation, gives you twenty-eight years required before you have a have at least one calendar for every possible day combination in a year.
Since my 'opened' calendar collection starts in 1980, 2005 was the 'magic' year for me. It was the final leap year necessary to complete the series of years. Beginning in 2005 every year forward would have a calendar in the past whose days would match the current year.
For instance, this year (2010) if you haven't purchased a calendar you can use the calendars from either 1982, 1993, or 1999. If you have purchased one already, keep it at the end of the year. It'll work for you again in 2021! 2016 is out because while January 1, 2016 is on a Friday, the same as this year, 2016 is a leap year so your 2010 calendar will only work through February in 2016. 2021 is the next year that full matches up. Can you hold onto an unopened 2010 calendar for eleven years? I'll bet you can!
At the left is a chart of compatible calendars all the way up through 2024. It would require charting an additional four and eight years before the calendars for 2000 and 2004 would be able to be used a second time.
