SDL and HKDL Refurb Calendars?

[Timchat2]

Are there any long-range refurbishment calendars for SDL and/or HKDL available online? I saw that HKDL lists attractions in its current daily calendar but that doesn't really help with planning out in the months ahead.

We were planning on a visit to both parks in May 2018 and we would really like to avoid missing attractions like Mystic Manor or Pirates of the Caribbean: Battle for the Sunken Treasure if we can help it.

Thank you!
