Better Late Than Never!

Is it a late Easter Cactus? Or a very late Christmas Cactus? Or a very, very early Christmas Cactus?

I've been waiting for days and days for the first flower to open. I used to call these Zygocactus truncatus, now they seem to be Schlumbergera truncata. Whichever it is, the colour and glossiness are natural and don't require my help in PS.

Do any flower at the appropriate season?
