Preloaded examplea wedding on February 20, 2027, with a reference date of November 20, 2026. There are 21 tasks: 1 overdue, 1 this week, and 3 in the next 4 weeks. Change the values to use your own details.
This tool requires JavaScript to calculate using your data. Without JavaScript, you can read the worked example on the right and the method below; nothing is sent to any server.
Your to-do list
Overdue (1)
This week (1)
Next 4 weeks (3)
Later on (14)
After the event (2)
Method: each task has a lead time in days before the event: these are planning suggestions, not requirements. Due date = event date − lead time, compared with your reference date. The suggestions are examples and do not replace requirements from your venue, vendors, or local authorities. Checked items are kept only while this page remains open.
How to use this tool
- Select the event type and enter its date; the reference date defaults to "today."
- Check off each task as it's completed and add any missing ones with their buffer in days.
- Download the CSV, import pending tasks to your calendar via ICS, or print the list.
How dates are calculated
For the example wedding (February 20, 2027), the task "Set maximum budget and event date" has a 90-day buffer: its deadline is November 22, 2026. Using November 20 as the reference date, there are 92 days until the event and the list contains 21 tasks, with 1 already overdue (checking requirements with the civil registry, which has a 120-day buffer).
Each task is sorted into "overdue," "this week" (up to 7 days), "next 4 weeks," or "later on," depending on how much time is left until its deadline.
Method, assumptions, and limitations
Deadline = event date − buffer in days. It is compared with your reference date: if it has passed and the task isn't completed, it shows up as overdue. The buffers are planning suggestions for each event type; you can add tasks with your own custom buffer (a negative number means after the event).
The ICS file creates an all-day event for each pending task. Checkmarks marking tasks as "done" only exist in this browser tab.
Keep in mind
- Buffers are guidance only and do not replace requirements from your venue, vendors, or local authorities.
- Official procedures (such as civil registry filings) vary by location: confirm deadlines directly with the relevant office.
- Your progress checkmarks are not saved when you close the tab; export the CSV to keep them.

Frequently asked questions
Are the deadlines mandatory?
No. They are planning buffers designed to keep you from rushing. Adjust them to your situation by adding your own tasks and dates.
What should I do if my event is only a few weeks away?
You will see several overdue tasks. Prioritize them by importance: venue, key vendors, and invitations first.
Can I add my own tasks?
Yes. Type in the task and how many days before the event it needs to be completed; you can also remove it.
How do I add the tasks to my calendar?
Download the ICS file and open it in your calendar app: it creates an all-day event for each pending task.
Is my progress saved?
Not automatically. The checkmarks only stay while you keep the tab open; download the CSV if you want to keep them.
