  Updated the "name" of this tool. It was a typo. Like, a very much arbitrary typo.

  Updated the limit for year. Dainder follows the rules for HTML5's input[type="date"].
• August 28, 2015
  Updated the method a bit so that Dainder can work more properly.

How to Use

• Type the year, month, and day (number) on each input, respectively. And the day name of that date will be displayed.
• Minimum year number is 1, and it can accept any other positive integer less than or equal to 275,760.
• Both month and day numbers start at 1.
  1^st month is January, and 1^st day is Sunday (not the date, but the weekday).
• Maximum month number is 12.
• Maximum day number is 31.
• To reset all, simply click/tap the reset button.

Additional Notes

• For day number beyond the month scope, for instance 2015-2-31, will be automatically-corrected to 2015-3-3.
  It's the wonder of ECMAScript (JavaScript).
  But of course, obvious weird date pattern will result error.
• For the year 275,760, the maximum month is September (9) and the day is 13. After that, it will set itself to January 1 (of 275,760).

The days were named after planets

Actually from the names of Roman's gods. We call them as "planets" now. By we, I mean books, mandatory knowledge. Back then, well, sometime ago, just plain star. Lights in the sky. Because it is, they are. Thank you for the brick.
