Wedding Checklist Printable and Spreadsheet, 12 Month Timeline Dated From Your Wedding Day

A wedding task list in two forms: a PDF to print, and a workbook that puts a date on every task from the wedding day you type in.

Print PDF, 11 pages in US Letter and A4: 90 tasks grouped from 12 months before to after the wedding, each with a box to tick and a Due line. There is a page for your own tasks and a vendor contact sheet to hand to whoever answers questions on the day.

Workbook, Checklist tab: the same 90 tasks with room for 150. Type your date on Setup and each task gets a due date and a weekday. Move the wedding date, and every due date moves with it. Change Months before or Extra days before to move one task.

Due Soon tab: what is late or due in your window, soonest first, with who is doing it.

Progress tab: done and left by month, by category and by person, with a chart.

The Example workbook has a made-up wedding part way through. The Blank workbook has the full task list and no dates.

COMPATIBILITY
An .xlsx workbook with ordinary formulas. No macros and no add-ins. A script recalculated it in LibreOffice 26.8 and compared the results with a separate Python calculation. Another script confirmed it uses no LAMBDA, LET, XLOOKUP or spill formulas. A script also opened this file in Microsoft Excel for Mac 16.114.3 and ran a full recalculation: every cell matched the values stored in the file, with no error cells. That test did not type new data into Excel or look at the screen. Excel for Windows and Google Sheets have not been tried, and the menu steps below have not been tried in Excel or Google Sheets. The PDFs are US Letter and A4. A script confirmed the fonts are embedded and the page links work, and that the ink stays at least 0.4 inches from the page edge. They have not been printed on a real printer yet.

QUESTIONS AND HOW-TO
Is the PDF dated?
No. It has Due lines for you to write on. The workbook does the dates.

What if my date is less than 12 months away?
Tasks already past show as Late on Due Soon. Mark the ones you have done with a date in Done on, or delete the row's task.

How does it count a month back from the 31st?
It lands on the last day of the shorter month, so 1 month before March 31 is February 28, or February 29 in a leap year.

Can I add my own tasks?
Yes. Use an empty row at the end of the Checklist table, and give it Months before or Extra days before. The PDF has a page for them too.

Does it tell me what I need for a marriage license?
No. It reminds you to ask your local office, because the rules differ from place to place.

Using this file in Excel
Open the .xlsx file. If a yellow bar says Protected View, click Enable Editing.
Type only in the colored input cells. The other cells hold formulas and are locked so they don't get overwritten by accident.
The Example file has made-up entries so you can see how it fills in. Start your own work in the Blank file.
Before you type anything, use File > Save As and give the Blank file a new name. That keeps a clean copy for next time.
To change a locked cell, go to Review > Unprotect Sheet. There is no password. If you edit a formula, the totals may stop being right.

Copying this file to Google Sheets
Open Google Sheets in a browser and start a blank spreadsheet.
Go to File > Import, choose the Upload tab and select the .xlsx file.
Under Import location choose Replace spreadsheet, then click Import data.
Your copy now lives in your own Google Drive. Name it with File > Rename.
Sheets may not keep the locks from the Excel file, so type only in the colored input cells.

Print settings for this PDF
Open the PDF in Adobe Acrobat Reader or Preview, not in a browser tab. Browsers can change the scale without telling you.
In the print window, pick the paper size that matches the file name.
In Acrobat Reader, set Page Sizing to Actual Size. In Preview, set Scale to 100%. If the edges get cut off, switch to Fit in Acrobat Reader or Scale to Fit in Preview.
Print one page first and check it before you print the rest.
To print only some pages, type the numbers in the Pages box, for example 3-8.
For double-sided pages, choose flip on long edge for portrait pages.

A4 or US Letter
US Letter is 8.5 x 11 inches (216 x 279 mm). It is the usual paper in the United States and Canada.
A4 is 210 x 297 mm (8.3 x 11.7 inches). It is the usual paper in most other countries.
The paper size is in each file name. Print the one that matches the paper in your printer.
If you only have the other size, use Fit or Scale to Fit in the print window. The page will come out slightly smaller, with wider margins.

HOW AI WAS USED
AI helped write the listing text, the how-to text, the task lists and the code that builds these files. Scripts tested every due date, weekday, status, the Due Soon list and the Progress tables, on 11 sets of test data including a wedding on February 29, a wedding on March 31 where a month back lands in a shorter month, a date already past, and tasks due exactly today. A script also tested that all 90 tasks are in both PDFs under the heading matching their timing in the workbook, that the fonts are embedded and that the page links work. No person is claimed to have checked it unless stated here.

PLEASE NOTE
The dates are a starting point, not a rule. This is a planning list, not legal advice. Ask your local office what it needs for a marriage license. License: for your personal use only. No resale or sharing of this file.
