"October tenth is a Tuesday."
I wish they had recorded the pronunciation for 日 as び instead of ひ. That pronunciation is used much more often for that kanji.
In terms of birthdays, anniversaries, and such, sure. But there are many other words that include the kanji that use ひ. 日焼き、日暮れ、日帰り、to name but a few are all ひ. The kanji by itself is also never び.
