According to Trust Central, Harmony Circle of the Central
Singapore Community Development Council (CDC), there are 10
official religions in Singapore.
Extracted from the website:
Singapore recognises 10 faiths as its official religions : Baha'i
faith, Buddhism, Christianity, Hinduism, Jainism, Judaism, Islam,
Sikhism, Taoism and Zoroastrianism.
For information on the 10 religions, please visit

I really didn't know that at all. Call me a frog in the well or
whatever, but it's really interesting and good to know about the
official religions in my own country.
10, quite a lot, in my opinion. Of the ten, I only know
Christianity, Hinduism, Islam, Taoist, Buddhism, Sikhism and
Judaism.
Guess I have lots to learn from here. 
How about the rest of you? How many among the official religions do
you know or have at least heard about?
Please share your views and knowledge with me.
