Reusable Calendar Project Update 4
Summary
Added the pre-Oct 1582 restriction on the reusable calendar. (Working version, Update 4 version)
Essentially, the addition from Update 3 is the function checkRestraint(), where it checks the date being dragged or clicked on to see if it should be set to Oct 1582 or let it be.
I also used the checkRestraint() function to make the cursor look normal when the mouse is over a date that should not be available, even though they can click on it, but it would just move to Oct 1582.
Check it out and let me know if it the functions don’t work properly or intuitively.

Calendar Strips Drag on a Grid
Summary
I isolated the dragging portion of update 3 of the reusable calendar project to show what options under the draggable jQuery UI to use.
In the draggable() function, I used the grid: [0, 15] to restrict its movement to 15 px vertical, then I used containment: [0, y1, 0, y2], where y1 is the offsetTop value of the strip itself when it’s at the last month/digit, and y2 is at the first month/digit, to restrict its range so the strip won’t go past the first and last value.
Reusable Calendar Project Update 3
Summary
Adding more functionalities to the date display to the reusable calendar. Now you can click on the months or year digits, or you can drag the strips to change the date. (Before, you can only click on the arrows move forward or backward one month at a time.)
This dragging function was made easily possible by the jQuery UI. It takes a lot of the grunt work out of the process.
Notes
The current range is Jan 1000 to Dec 9999. But technically, the calendar doesn’t apply before October 15, 1582, since that’s when the Gregorian calendar was first adopted. So I will add that restriction in the next or upcoming updates.
Reusable Calendar Project Update 1
I mentioned in my latest monthly update on Flush that I am working on a special calendar that I will hopefully display on the home page of the website when it’s all done. Here is a screenshot of the basic set up I have so far:
It might look a bit complicated, but the concept is delightfully simple (to me at least). I will probably explain more in detail later on, but basically, the idea is that with the set up on the left, you can generate any layout of the month we see in practically all calendars in the world.
