The Chingay parade is held of the 21st day of the Chinese New year. In 2014 that will be February 20th.
Here are my photos from 2013 Chingay afternoon parade. The afternoon parade starts at 11 AM or so on the previous day – so on February 19th this year) as deity statues from the Old Chinese Temple are carried out to get ready for the evening parade.
The biggest parade is the night parade but there is also a parade during the day. The evening parade covers 10 km and starts about 7 PM, I believe; it will finish after midnight.
The Johor Bahru parade is also called The Parade of the Deities as the Temple deity statues are taken on a journey from the Temple to bless the city with peace, prosperity and harmony (the Chingay parades in Singapore and Penang are non-secular as I understand it).
