The Twin Birthdays - new resource

We are happy to announce the availability of a new presentation on one of the great festivals of the Baháʼí calendar: The Twin Holy Days or The Twin Birthdays.

These are the anniversaries of the births of the Báb and Bahá’u’lláh, which occur on consecutive days and so are known as The Twin Holy Days.

The presentation explains the significance and timing of The Twin Birthdays and includes images of celebrations from around the world. It has links to further resources.

The presentation, which will probably work best for secondary students, can be found on the Baháʼí Calendar page here.

The Twin Holy Days will be celebrated this year on 10th and 11th November 2026.
