What does my name mean?

People sometimes ask me what my stage name - Diane Kichijitsu (ダイアン吉日)– means.
It's a play on the words 'Daian Kichijitsu' - A day that is considered to be lucky. People in Japan often check the  calendar to look for a Daian/Taian Kichijitsu day before making plans for a special occasion, especially weddings. This means that I'm lucky every day. Lucky Day Diane.
