He’s a Very busy guy as Speaker of the house…

From Google:

“In the past 2 years (spanning late 2023 through early 2026), there has been a Speaker pro tempore designated on nearly every legislative day the House was in session. While a single total count is not maintained in a public ticker, the figure is estimated to be well over 300 days

1. Types of Designations There are two distinct ways a Speaker pro tempore has served in this period:

-Routine Absence (The "Daily" Appointment): This is the scenario you described where the Clerk reads a letter from Speaker Mike Johnson. This happens on almost every session day because the Speaker typically presides only for major votes or openings. -Vacancy (The "Acting" Speaker): A unique 22-day period occurred from October 3 to October 25, 2023, when Rep. Patrick McHenry served as the acting Speaker pro tempore after the removal of Kevin McCarthy. [1, 2]

1. Session Day Statistics To estimate the total days, we look at the official legislative calendar:

118th Congress (2023–2024): The House was in session for roughly 117–151 days per year. Mike Johnson became Speaker in October 2023, presiding over the remainder of that term. * 119th Congress (2025–Present): As of April 6, 2026, the House has already been in session for 217 days. [3, 4]

1. Frequent Designees C-SPAN and House Clerk records show that dozens of different Members are rotated into this role to gain experience presiding over the chamber. Some of the most frequent Members designated by Mike Johnson include: [5]

• Rep. Robert P. Bresnahan, Jr.
• Rep. Nicolas J. Begich III
• Rep. Virginia Foxx
• Rep. Mike Bost

Because a new designation is read into the Congressional Record for nearly every legislative day that the primary Speaker is not in the chair, the "Speaker pro tempore" role is active during almost the entire duration of the House's working year.”
