Bullet Journal 101: Modules, Logs, and Migration

Happy Canada Day, and welcome back to Bullet Journal 101!

Last week, we looked at the basics of a bullet journal. This week, we’re looking at how you can expand out from your to-do lists to create a larger, more complex, and more specialised system for your BuJo.

The official website talks about Modules, Logs, and Migration, but only briefly, so I’ll cover them again here for clarity’s sake.


Modules include everything in your BuJo. A log is a module. The index is a module. Your habit tracker is a module. All of your collections are modules. Modules are to clothes as logs and collections are to shirts and pants. Logs and collections are modules. Shirts and pants are clothes. It’s a category for all the crap you’re putting in your notebook.


Logs deal with time-sensitive items. You can create a “Future Log” like the one on the website, where you write down events, tasks, and reminders in a calendar spread for the future, but with less detail than the “Monthly Log.” The monthly log is a list of all the days in the month, and then relevant information is stored there. The BuJo website classifies daily to-do lists as “Daily Logs,” so any tasks, events, and reminders that are linked to a specific day are considered to be part of a log.

Another way to look at logs is to see them as calendars. A four-month semester-long calendar is a semester log. A three-month calendar is a quarter log for your blog or business. A calendar for one month is a monthly log. A series of rows and columns that have a space for each day of each month for an entire year can be used for tracking your habits or quality of life—and this is also a log. A yearly habit log, perhaps.

A large chunk of the BuJo community finds most of their inspiration and creativity inside their logs and collections. You can mix and match, create your own, and cater all of your logs and collections to your specific needs.


All the information in your BuJo, whether it’s a task that needs to be done or an inspiring quote you noted on a day, needs to be migrated to a more permanent space, like a collection. Migration deals with the list items from your daily logs that don’t have a “done” or “in progress” status. Tasks not done on one day can be migrated to the next day, or they can be scheduled for another day. Signifiers and bullets can tell you whether the task is moved to tomorrow or scheduled farther in the future. Notes and reminders, or quotes you jot down, can be done in the daily log and then migrated to the appropriate collection or calendar.

So let’s say I have a daily log. In it, I write, “Even behind clouds, the sun will rise”—a motivational and inspiring quote. I also write, “Brother visits July 3rd to July 12th.”

At a designated time, maybe at the end of the day or the end of the week, I would flip through my daily logs and find pertinent information to transfer to a collection or a different log. I’d move my quote to a Quotes collection, and write down in a monthly log the days my brother is in town.

Personally, migration doesn’t work for me. It’s an additional step that takes away from my organisation; I’d rather go straight to the collection or log and write down the information.

However, if I have a task or an event written in one daily log that I don’t do that day, or that gets post-poned, I can migrate it to the next day, or I can add it to a monthly or weekly log, or even add it to a collection like “Housekeeping and Home Improvement.” I have yet to find a rational way to cross-reference a monthly log with my daily logs to try implementing migration. Just goes to show that I’m still learning with you!

If you can believe it, we’ve covered the basics already. You now have all the information necessary to go full-force into a bullet journal. You know about bullets, collections, modules, logs, and migration. If you’re confident enough, you can stray from the purist path. If not, I suggest you use the method on the website to see what doesn’t work. Start with the process of elimination.

This week’s challenge

Create a monthly log for July. You can use the design on the BuJo website, or do a look on Pinterest and Instagram for ideas. I have a Pinterest board for the bullet journal in case you need inspiration. Think about how much information you need to include in your log. You can also write out the things you want to display in your monthly log. Maybe a list like the original system will work for you. Maybe you need a column-and-row box calendar instead.

Here is what I’ve designed for my July Log!

Next week will feature all the goodies you can have fun with in the core of the bullet journal—Daily Logs. I’ll share some of my own daily log spreads so you can see what I started with and how my layouts changed.
