What is the best save the date wording for a bat mitzvah?

A bat mitzvah is a religious coming-of-age ceremony, so the wording should reflect that significance while being practical. Start with the child's full Hebrew and English name if that is traditional for your community, then her parents' names. Include the date, the synagogue or venue, and a note that a formal invitation with service times and reception details will follow. You can add 'Please join us for this simcha' or 'We look forward to celebrating with you', but keep it simple. If the ceremony is on a Saturday morning and the reception later, guests will need to know that the day is long, so you might write 'Save the full day' or 'Save the date for the service and celebration'. Avoid mentioning gifts or charity on the save the date; that belongs on the invitation or a separate note. If you are unsure about the exact synagogue name or address, check with the family or the rabbi. The tone should be warm and inclusive, welcoming all guests regardless of their own faith background.
