"July seventh is a Friday."
These "write this in japanese" exercises could really do with a sound button after giving the answer, so that we can hear the pronunciation. Learners are missing out if they forget to check discussions to hear the pronunciations. I think it's very important especially in lessons that present exceptions to the rule. The months of April, July and September have a different reading from the typical. Also if we get into the "20th" later (don't know, I'm a slowpoke, not there yet) for example, sound is essential with the correct pronunciation of course, deduction would make us think the wrong thing while the voice would steer us in the right direction.
edit: and literally the next phrase I get shows 20th, do I feel stupid now -___- However the "20th" was fractured between number and counter in the choices so I guess that's a way to make learners remember the exception? Good thing the voice pronounces it correctly. GJ duo!
