Lock Date Time Memo

When you go out and lock your home door, you can use this application and remember date and time by simple operation.
If you are anxious about whether the door is locked, you can use this application and confirm the day and time when you have locked and trust you have locked.

I made this because I would like not to mind whether I have locked.
If you always use this after you have locked, you feel the peace of mind more.

The latest day and time is colored red.

You can choose the representation of the day from the following five types
- 1999/12/31 Fri
- Fri 31/12/1999
- 12/31/1999 (Fri)
- Fri 31 Dec 1999
- Dec 31, 1999 (Fri)
