Schedule lists today's calendar events, merged with two things from your vault:

• Meeting notes dated today. When a meeting note matches a calendar event, they appear as one row.
• Time blocks: a checkbox in today's note beginning with a time, such as - [ ] 1:00 PM – 2:00 PM Lunch with Priya. Header shows it in Schedule instead of treating it as a task.

Click a row that has a note to open it. To see calendar events, Today needs Calendar access. The first time, the Schedule section shows Show today's calendar here. with a Connect Calendar button; that button is the only place Today asks macOS for permission. If access was turned off, the row offers Open System Settings instead. Click the small × to hide the row until Header restarts.

The switch for all of this is Settings → Calendar → Use Calendar in Today and Minutes, on unless you turn it off. Calendar is read on this Mac and never synced. With it off, Today shows no events and never asks.

If you keep some to-dos in Apple Reminders, Today can show the ones due today or overdue in a From Reminders section, with the list name and the time (or Today, or Overdue). The section is read-only. Click a reminder to open it in the Reminders app and tick it there.

It's off until you turn on Settings → Calendar → Show Apple Reminders on Today. Turning it on asks macOS for Reminders access; the switch shows Allowed once it's granted.

Tasks that are overdue by more than a week, and tasks flagged #priority, #urgent, ⏫ or 🔺 with no date, don't crowd Needs you. Instead, one quiet line says something like 4 older tasks are overdue or flagged. Click Review to open Older tasks, grouped into Overdue more than a week and Flagged, no date.

Decide about each one with Done, Today, Later or Drop, or select several and use Add to Today, Later until… or Drop Selected… at the bottom. Before a bulk drop, Header tells you how many notes will get [-]. Nothing in this list changes on its own.

Later offers Tomorrow, Next Monday, In Two Weeks or Pick a Date… (choose a day under Bring it back on, then click Move to Later). The task disappears from Today until that day, then comes back marked Back from Later. Its note isn't touched; the decision is recorded in today's daily note.

Drop is for tasks you've decided not to do. Header changes the checkbox to [-] in its note and records the drop in today's daily note, so Today stops asking. If the drop can't be recorded, Header puts the checkbox back.

After any change on Today, a message at the bottom of the page offers Undo for a few seconds.

Today keeps its record under a ## Today heading in today's daily note. If that note doesn't exist yet, Header creates it from your daily template the first time you add, focus, defer or drop something. The list lines are plain bullets with a link back to the task's note; the Closed record names tasks by their text. None of them are checkbox copies, so your tasks aren't duplicated and the note reads fine in any Markdown app:

In the task's own note, Today changes only the checkbox: [ ] to [x] when you mark it done (and back when you reopen it), or to [-] when you drop it. Your own lines under ## Today are left alone. If you've edited one of Header's lines by hand, Today refuses to overwrite it and tells you, rather than guessing. Today doesn't use AI, doesn't create your daily note when you only look at the page, and doesn't move or rename notes.

The ⋯ button at the top right of Today has Refresh Today and Personalize greeting…. In the greeting popover, turn on Personalize the greeting and type a Display name. It's stored only on this Mac, never written into notes or sent to an AI provider.

Choose File → Open Today's Note (⇧⌥⌘D), click Open today's note at the top of Today, pick Open Today's Note in ⌘K, or open header://daily. If today's note doesn't exist, Header creates it from your daily template first. It never overwrites an existing note, including one that's still downloading from iCloud.

Without a template, a new daily note gets a few properties, the date as its title, links to yesterday's and tomorrow's notes, a Today’s Focus heading and a Notes heading.

To browse past days, open Library → Daily Notes in the sidebar. It lists notes whose path includes Daily, Journal or Diary, and notes whose title is a date.

Header works out where each vault's daily notes go, in this order:

1. Your own setting for this vault, if you've saved one (below).
2. The Obsidian Periodic Notes plugin's daily settings, when that plugin is set up in the vault with daily notes turned on.
3. Obsidian's core Daily notes settings (folder, date format and template), when the vault has them and that plugin isn't turned off.
4. Otherwise, Header's default: a folder called Daily Notes, 01 Daily Notes, Daily or Journal if you have one, or a new Daily Notes folder, with notes named by date.

So if you came from Obsidian, Header uses the same folder, date format and template you already had. To see or change it, open Settings → General → Today. The Daily notes row shows the folder and date pattern in use and where they came from, for example “(from Obsidian Daily Notes)”. Click Change… to set:

• Folder: leave it empty for the top of the vault.
• Date format: YYYY-MM-DD unless you change it. It uses date tokens like YYYY, MM and DD, and slashes make folders, so YYYY/MM/YYYY-MM-DD files each day inside year and month folders.
• Template: the path of a note to copy for each new day, such as Templates/Daily.md.

The sheet previews today's path before you click Save. Use detected settings removes your setting and goes back to the order above. Your choice is saved inside the vault in .header/daily-notes.json, so it travels with the vault. Today's Note, Today's records and the Daily Note capture destination all use this location.

A template can use {{title}}, {{date}}, {{time}}, {{date:FORMAT}} and {{cursor}} the way Obsidian's templates do, plus {{yesterday}} and {{tomorrow}} for the neighbouring dates. If Header is using its own default location and no template is set, it looks for Daily.md or Daily Note.md in your Templates folder.
