Here\u2019s how to do it step by step.\n\n---\n\n## Key NeoMutt Pattern Tools\n\nNeoMutt supports several useful pattern operators for selecting messages, including:\n\n- `~d MIN\u00ad-MAX` \u2014 matches messages whose **\u201cdate-sent\u201d** falls within an absolute date range. ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))  \n- `~r MIN\u00ad-MAX` \u2014 similar, but based on the **\u201cdate-received\u201d** field. ([neomutt.org](https://neomutt.org/guide/advancedusage.html?utm_source=openai))  \n- `~A` \u2014 matches *all* messages. ([neomutt.org](https://neomutt.org/guide/advancedusage.html?utm_source=openai))  \n\nThese can be used with commands like `tag-pattern` to mark a group of messages, or `delete-pattern` to mark them for deletion directly. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))\n\n---\n\n## Example: Delete All Messages from a Given Year\n\nAssume you want to delete **all messages from the year 2022** in the current mailbox. Here are two approaches.\n\n---\n\n### Approach A: Using `tag-pattern` then delete\n\n1. Open the mailbox you want to cleanse (e.g. your Inbox).\n2. Tag every message from 2022:\n   ```\n   T ~d 1/1/2022-12/31/2022\n   ```\n   (`T` is `tag-pattern`; default binding is `Shift-T`) ([neomutt.org](https://neomutt.org/guide/advancedusage.html?utm_source=openai))\n\n3. Then delete the tagged messages:\n   ```\n   ;d\n   ```\n   This applies the `d` (delete) command to all tagged messages. ([neomutt.org](https://neomutt.org/guide/advancedusage.html?utm_source=openai))\n\n4. Finally, quit or sync the mailbox so deletions are committed.\n\n---\n\n### Approach B: Using `delete-pattern` directly\n\nIf you want to skip tagging, you can use:\n\n```\ndelete-pattern ~d 1/1/2022-12/31/2022\n```\n\nThis marks for deletion every message whose \u201cdate-sent\u201d is in 2022. After that, quit/sync to commit deletions. ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))\n\n---\n\n## Notes, Tips & Variations\n\n- **Date format:** You can use `DD/MM/YY`, `DD/MM/YYYY`, or `YYYYMMDD`. For example, `~d 20220101-20221231` also works. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))  \n- **End-inclusivity:** The range `1/1/2022-12/31/2022` includes both days. If you want \u201cup to but not including\u201d Jan 1, 2023, you can replace the end date with `-20230101`. Similarly, leaving out the end date (`1/1/2022-`) will select *from* Jan 1, 2022 to the most recent message. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))  \n- **Deleting vs expunging:** Pressing `d` or using `delete-pattern` only *marks* messages for deletion. Depending on your mailbox type (mbox / IMAP / Maildir), you may need to \u201cquit\u201d NeoMutt, use its sync, or issue an expunge command so they're actually removed.  \n- **Backup first:** Since this operation affects many messages, it's smart to backup or move messages instead of immediately deleting \u2014 just in case.\n\n---\n\nIf you tell me your mailbox type (e.g. IMAP, Maildir, mbox) I can give you a more tailored version of this so you don\u2019t accidentally lose something you wanted to keep."

        "content": "Not exactly \u2014 NeoMutt doesn\u2019t require the \u201cYYYY/MM/DD\u201d format with slashes in that specific order when using `~d` (date-sent) or `~r` (date-received) patterns; the acceptable formats are a bit looser. Here\u2019s how it works, based on the current NeoMutt manual.\n\n---\n\n## \u2705 Acceptable Date Formats in NeoMutt\n\nFrom NeoMutt\u2019s documentation:\n\n- Absolute dates can be given in `DD[/MM[/[CC]YY]]` format. That means:\n  - You **must** provide the day (`DD`).\n  - The month (`MM`) is optional (defaults to current month if omitted).\n  - The year (`YY`) is optional (defaults to current year), but if provided, can be two- or four-digit, with rules for interpreting two-digit years. ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))\n  - Four-digit (or full) year format is also supported via `YYYYMMDD` (without slashes). ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))\n\n---\n\n## \ud83d\udee0 Date Range Syntax\n\n- To specify a **range**, you give two dates separated by a hyphen (`-`), like `MIN-MAX`. Each of those can follow the above formats. ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))\n- Examples:\n  - `~d 1/1/2022-31/12/2022` (day/month/year each): all of 2022.  \n  - `~d 20220101-20221231` (YYYYMMDD format): also all of 2022. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))\n- If you omit the **minimum (first)** date: `-31/12/2022` \u2192 all messages **up to** Dec 31, 2022. ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))\n- If you omit the **maximum (second)** date: `1/1/2022-` \u2192 all messages **on or after** Jan 1, 2022. ([neomutt.org](https://neomutt.org/man/neomuttrc?utm_source=openai))\n\n---\n\n## \u26a0 What \u201cYYYY/MM/DD\u201d Doesn\u2019t Work\n\n- While `YYYYMMDD` *without slashes* is valid, `YYYY/MM/DD` (with slashes) **is not** the documented format for four-digit years. NeoMutt expects either the `DD/MM/...` style (with optional fields) *or* the concatenated `YYYYMMDD` for full precision. ([neomutt.org](https://neomutt.org/guide/advancedusage?utm_source=openai))\n\n---\n\n## \ud83d\udd0d So, for Your Case\n\nIf you want to delete all messages from **year 2022**, you could use either:\n\n- `~d 1/1/2022-31/12/2022` \u2014 full day/month/year style.  \n- `~d 20220101-20221231` \u2014 concatenated YYYYMMDD style.\n\nAnd then use one of the delete methods (e.g. `delete-pattern` or `tag-pattern` + `;d`) to mark them for deletion.  \n\n---\n\nIf you want, I can craft the exact commands you should run in your NeoMutt setup to do that safely \u2014 just to make sure nothing unexpected happens."

        "content": "Yes \u2014 in NeoMutt you *can* use `D` with a pattern to delete messages, without first tagging them with `T` then using `;d`. The `D` command is bound by default to \u201cdelete-pattern\u201d which applies the deletion flag to all messages matching your pattern in one step. ([neomutt.org](https://neomutt.org/guide/reference.html?utm_source=openai))\n\n---\n\nHere\u2019s a breakdown of how `D` works and how it compares vs using `T` + `;d`.\n\n---\n\n## \ud83e\uddf0 What `D` (delete-pattern) Does\n\n- The `D` key is by default bound to `delete-pattern`, meaning: \u201cmark all messages matching a given pattern (e.g. date range, sender, etc.) as deleted.\u201d ([stackoverflow.com](https://stackoverflow.com/questions/49476747/filter-delete-emails-in-neomutt-without-external-tools?utm_source=openai))  \n- These deletions are *marks*, so you can still undelete them (e.g. using `u`) until you exit or synchronize the mailbox. ([manpages.debian.org](https://manpages.debian.org/buster/neomutt/neomutt.1.en.html?utm_source=openai))\n\n---\n\n## \ud83d\udd04 Versus Using Tag + `;d`\n\n| Method | Steps required | Pros | Cons |\n|---|---|---|---|\n| `D pattern` | One step: press `D`, enter the pattern (e.g. `~d 20220101-20221231`) | Fast, efficient; no need for tagging first. | More risky\u2014if your pattern is wrong, you mark more or less than intended; less previewing. |\n| `T pattern` then `;d` | Two steps: tag matching messages (`T pattern`), then delete tagged messages (`;d`) | Safer \u2014 you can see exactly what you're about to delete before doing it; more control. | More keystrokes / overhead. |\n\n---\n\n## \ud83d\udcc5 Pattern Example\n\nIf you want to delete all messages from the year **2022**, using `D` you could do:\n\n```\nD ~d 20220101-20221231\n```\n\nThat will mark *all* messages from that date-sent range as deleted, without needing to tag first. Then you exit or sync to commit.\n\n---\n\n## \u26a0 Warnings & Tips\n\n- Always make sure your pattern is correct. With `D`, you\u2019re doing it all in one step.\n- If you\u2019re uncertain, it's safer to use the tag + delete approach (`T pattern`, inspect, then `;d`).\n- After marking with `D`, messages may still be visible (depending on settings); undeletion with `u` can restore them until the mailbox is closed/collapsed/synced. ([manpages.debian.org](https://manpages.debian.org/buster/neomutt/neomutt.1.en.html?utm_source=openai))\n\n---\n\nIf you want, I can walk you through what your pattern might look like (based on your mailbox dates) and how to preview before you use `D`, so you don\u2019t accidentally delete too much."
