The Light of Divine Guidance (Volume 2)

Regarding the time to hold the 19 Day Feasts: any time most convenient for all the believers is permissible, as long as it is between sunset and sunset of the calendar day on which the feast 60 falls, as our Bahá’í days begin and end at sunset. The feasts are really for the believers only, but if a non-Bahá’í happens to come, we should not ask him to leave and hurt the person’s feelings.
