Bus Service 405 connects Choa Chu Kang Cemetery, Crematorium and Columbariums with Boon Lay MRT/Bus Interchange, serving parts of Old Choa Chu Kang Road and Lim Chu Kang Road without a regular bus service.
This service operates only during specific periods: the Qing Ming Festival, Good Friday, the start of Ramadan, Hari Raya Puasa, Hari Raya Haji, the Deepavali period, and All Souls' Day. The exact operating dates are announced by the bus operator closer to each year's start of service.
Service 405 features two unique U-turn points. The first is at the end of Old Choa Chu Kang Road, at the junction with Jalan Sungei Poyan, where a three-point turn is performed. The second is on Lim Chu Kang Road, just before Murai Farmway, where a special "Bus-only" U-turn bay is utilized.
On certain days with exceptionally high traffic on Old Choa Chu Kang Road, buses may be diverted to skip this road altogether, looping at Lim Chu Kang Road before returning to Boon Lay.
During the Singapore SEA Games in June 2015, a special variant of Service 405, known as Service 405M, ran for six days to serve the National Shooting Centre on Old Choa Chu Kang Road, bypassing the Lim Chu Kang Road section of the route.

405 2022 dates just dropped m8 https://www.sbstransit.com.sg/news/service-405—operating-dates-in-2022
I agree with extending 405 to daily and extending to LCK road end (or maybe operating only at periods where 975 have high demand) to reduce the load on 975. It also connects to Boon Lay MRT which is more convenient for those living along East-West line as opposed to taking 975 to CCK and transferring at JE (And I think Boon Lay MRT is closer than CCK MRT from LCK).
I am also thinking about the feasibility to extend to Kranji MRT via Neo Tiew Road -> SG Buloh -> Skips bus stops along Kranji Way and Kranji Road to reduce duplication with 925 -> Kranji MRT (Loop). This helps to allow access to Kranji farms and connect LCK to Kranji MRT, which might also be nearer as compared to CCK
