jewish calendar is based on the lunar and solar calendar. (352 and 365 days) thats why jewish holidays are always around the same time of solar year. ie passover is always in the spring.
I updated the 95xx hebrew.jad file if any storm users want to test it. i believe it will allow you to choose to have a hebrew menu. and possibly names by the icons in hebrew. Index of /blackberry/95xx
let me know...i do not have a storm and i am curious. there were three additional he.cod files i found for the storm.
