3rd Day of 8 Lunar Month (農曆八月初三日) is consider as the Birthday of Bei Dou Xing Jun 北斗星君 (The Lord of the Great Northern Dipper), which in our Taoist Context, he's one of the few Deities that can set/control one's life and death, fortune, luck, etc.
In the Taoist Scripture "Bei Dou Jing 北斗經" describes, on the day of Bei Dou Xing Jun's birthday and other Feast Day of the Dou (齋日), if you will to recite Bei Dou Scripture (北斗經) or the mantra (寶誥), one will get his blessing and if someone will to pay respect to Bei Dou on behalf of his/her parent (父母求壽) or their love-one, the whole family will be blessed with Longevity and good fortune for the year.
If you are keen and sincere enough, after 11.00pm (Chinese Hour - Hai) tonight (2 Day of 8 Lunar 農曆八月初二亥時后), just prepare 3 cups of good tea (三杯香茗) and some simple offerings (5 oranges or Tea Leaves and Jian Hup 桔子或餞盒), place them at the Altar where you pay respect to the Heaven (天公桌/天官案), sincerely kneel down before the Urn and made your request to Bei Dou Xing Jun (best if you can recite his Praise Mantra 寶誥), Bei Dou Xing Jun will definitely be able to get your message and blessed you accordingly (paying respect on behalf of Parents, remember to recite their chinese name and Ba Zi).
Remember hor, must be sincere and respectful, if not your requests won't be answered.
Good Luck & Wu Liang Shou.
