Where can I buy a yellow calendar in Hong Kong?

If you want to buy an almanac, you can buy it at all the newsstands in the streets. If you want to be flat, you can buy it in Mong Kok Market, which is a market next to langham place. Where can you buy food, fruit, dry goods, etc. Go in and sell clothes and calendars. Almanac is sold at the stalls where you buy incense. In addition to the market, it can be sold in those places where you buy gold ingots, but don't go there.
