While I have found this guide very helpful each year for many years now, the 2025 guide has incorrect dates on when to switch from one volume to the next. For example, as I write this review on February 11th, 2025, we are in Volume III of the LOH. The guide says to switch to Volume II on February 22nd. That is not correct, and the switch should only occur on Ash Wednesday. The interesting thing is, the page number references in the guide for February 22nd and beyond to Ash Wednesday are correct for Volume III. Only the placement of when the switch of volumes needs to occur is incorrect.
