Convert Three Dated Planner to Undated

I have a single PDF planner that spans well over 100 pages and is currently structured as a yearly, date-specific layout. I simply need every reference to specific calendar dates removed so the file functions as a reusable daily planner. All other elements—graphics, tables, margins, and overall formatting—must remain exactly as they are now, page after page, so users will not notice any shift in design or alignment when they print.

What I will provide:
• The original, high-resolution PDF

What I expect back:
• A clean, press-ready PDF in the same page count and order, now fully undated
• No loss in image quality, text clarity, hyperlinks, or internal bookmarks that may exist
• Consistent fonts, line weights, and spacing across all pages after dates are stripped out

I work on both Mac and Windows, so the final file should open flawlessly in Adobe Acrobat and other standard PDF readers without triggering font substitution warnings or re-flow issues.

If you have an efficient workflow in Adobe InDesign, Acrobat Pro, Affinity Publisher, or comparable tools that lets you automate bulk text edits while preserving layer integrity, let me know—speed is welcome as long as quality is preserved.
