Is there a Jewish way for me to celebrate my birthday?
Answer:
Sure, there's a Jewish way for everything!
Here are some ideas (culled from the teachings of the Rebbe):
Note: All these suggestions should be implemented on your Jewish birthday. Use our Jewish/Civil Date Converter to find out when your Jewish birthday is.
Giving charity should be a daily event. On your special day increase the amount of your contribution, especially before the day's morning and afternoon prayers. If your birthday falls on Shabbat or a Jewish holiday when handling money is forbidden, give the added charity beforehand and afterwards.
Spend some extra time praying, focusing on meditating and concentrating on the words of the prayers.
Say as many Psalms as possible. Ideally you should complete at least one of its five books (Psalms is divided into five books).
Study the Psalm which corresponds to your new year. This is your age plus one -- e.g. Psalm 25 if this is your 24th birthday. Click here to study it online. This is also the Psalm which you should try to say daily until your next birthday.
Take some time out to contemplate on your past year. Consider which areas require improvement, and resolve to do so.
Learn some extra Torah on this day.
Study a Chassidic idea and repeat it at a gathering in honor of your birthday. Follow the following links for Short Insights, or some Essays.
Partake of a new fruit which you did not yet taste during this season and recite the Shehecheyanu blessing.

Men and boys over the age of thirteen: On the Shabbat beforehand, get an aliyah in the synagogue. If the birthday falls on a day when the Torah is read, be sure to receive an aliyah on that day too.
