日期是星期几？今天星期几？日期 asks for month and day number. 星期几 asks for the weekday. Mixing them sounds like asking two different things at once.
Can 日期 mean 'day of the week'?
No. 日期 is the calendar date, not the weekday.
日期 means the month and day number on a calendar. 星期几 asks for the weekday, like Monday or Friday. Mixing them creates a category error, so 日期是星期几 sounds off. For the date, ask 今天几月几号. For the weekday, ask 今天星期几.

Why do Chinese people ask 今天几号 instead of 今天的日期是什么?
Real people say 今天几号; 今天的日期是什么 sounds like a form.

In 问日期，几月几？
Dropping 号 in 几月几 is normal casual shorthand, not an error.
In relaxed speech, 几月几号 often gets shortened to 几月几. The dropped 号 is understood from context, so nothing feels missing. This is common in quick questions between friends or coworkers. For forms or careful writing, keep the full 几月几号. “问日期，几月几？” (To ask the date, say 'What month and what day?') ── [《问问题》](/read/asking-questions-daily-life#s2)
| Dimension | Natural | Avoid |
|---|---|---|
| Casual speech | 今天几月几？ | 今天几月？ (asks month only) |
| Full date | 今天几月几号？ | 今天几月几？ (too casual in forms) |
