First thing first, in daily life, modern Chinese people use just the Arabic digits. So as a native speaker of Chinese, I feel weird when see you guys use so many Chinese numbers.
In daily life, we use Chinese character to represent number in the receipt or bank things to confirm the digits are not changed, and we have a set of "大写数字" for money thing:
- 壹 1
- 贰 2
- 叁 3
- 肆 4
- 伍 5
- 陆 6
- 柒 7
- 捌 8
- 玖 9
- 零 0
- 拾 10
- 佰 100
- 仟 1000
- 万 1 0000
- 亿 1 0000 0000
(Notice that in Chinese we add space every 4 digits)
For time, it is also the case: in daily life, use Arabic digits. Just remember unlike in English, in Chinese, we say things from big to small. This "zoom in" rule is good for all range-ish concepts.(Time, date, address).

Also, in daily life, Chinese Character date are sometimes used. We use "元月" for January sometimes ("一月" is of course right and more common), and "〇" for zero.
