MitzvahWise: clear answers on bat and bar mitzvah gifts, how much to give, what to wear, and every Jewish holiday.

Straight answers for a lovely, slightly intimidating invitation: how much money to give and why it comes in eighteens, what to wear to the service versus the party, what to write in the card, and what will actually happen in the sanctuary. Written for guests first, families second, with the customs explained rather than assumed.

Reference tools: the gift amount calculator (chai-multiple math by relationship) · the card message library (copy-ready lines by relationship) · the holiday calendar (every date, what it is, whether you bring a gift).

This site started as the notes we kept passing to friends before their first bat mitzvah: how much to put in the card, what to wear to shul, when to stand, what mazel tov actually means. It grew into a full guide to the gifts, the etiquette, and the holidays. If a custom varies by community, we say so on the page.
