There is something I don't understand now...
What is the difference between these two letters??

I know this one is つ　tu
But what is this smaller one っ? I can't find it on the keyboard..
Just like the one in mikka , yokka.
みっか
よっか

And check out this Power Point work by me, I have just made it now.
1. Days of the Month - From 1st to 10th.pptx

I also made a way to memorize the days from 11th to 19th, pretty easy I think and if you saw it as well, Sumippi, I hope it will be of help to you so you don't get confused.

The days from 11th to 19th starts with juu and ends in nichi, except for that 14th starts in juu as well but it is just like 4th ends in yokka...
juuyokka

Let's see what we will do next...!!
Remember the song I have just made..
(san - shi - goga - roku - shichi - hachi - kuga)
(1) Now remove shi from the list.
(2) Now remove ga from goga, and remove ga from kuga.

Days of 11th and 12th
11th : We will add ichi from January or it's just number 1 ichi ichigatsu, we will just add it after juu.
juuichinichi.

12th : We will add ni from February or it's just number 2 nigatsu, and we will just add it after juu,
juuninichi.

Now the rest in the list of the song, we will add them after juu for days of 13th to 19th except 14th in same order.

Let's try and see.
13th: juusannichi
15th: juugonichi
16th: juurokunichi
17th: juushichinichi
18th: juuhachinichi
19th: juukunichi

And here is another Power Point work by me for days from 11th to 19th this time.
2. Days of the Month - From 11th to 19th.pptx

And ohh.....!!!!
After I have discovered a new and simple way rather than this I discovered that forming Japanese numbers are so so so so easy than I expected... You don't have to be confused...
I think the only one is different is just 4---- numbers and numbers like 20, 30, 40, 50, etc.......
