How to Schedule a Post on X (Twitter): Web, iPhone & Fixes

To schedule a post on X, open the composer on x.com, write your post, click the calendar icon in the toolbar, choose a date and time, click Confirm, and then click Schedule. The post is stored by X and goes out at the time you picked. On iPhone, X began rolling out the same calendar icon in the post composer in September 2026; Android had not received it in the versions reported at the time.

That’s the short version. The details are where people get stuck: where scheduled posts are stored, how drafts differ, what you can change after scheduling, and why a post sometimes seems to vanish. This guide covers all of it, plus a simple weekly routine. A note on sources: X’s help center documents scheduling for X Pro and the ads composer but doesn’t have a page for the standard composer, so for those steps we rely on the current interface and on news and testing reports, and we say so where it matters.

How to schedule a post on the web

This is the most reliable route and the one that has existed longest.

1. Open x.com and click Post to open the composer (or click into the compose box on your home timeline).
2. Write your post and add any images or video as you normally would.
3. Click the calendar icon in the toolbar under the text box.
4. Pick the date and time, then click Confirm.
5. Click Schedule. The Post button changes to Schedule once a time is set, so you can see the post won’t go out immediately.

Double-check the date before confirming. A wrong month or a 12-hour clock mix-up (AM instead of PM) is the most common reason a “scheduled” post goes out at the wrong time.

How to schedule a post on mobile

X’s help center has no page on mobile scheduling, so this part comes from news reports. On September 5, 2026, Benji Taylor, who works on design at X, announced that scheduled posts were starting to roll out in the mobile app. Reports from testing found it in the iOS app but not in the Android app.

If you’re on iPhone, update the app, open the post composer and look for the calendar icon. If it’s there, expect it to work much like the web: write the post, tap the calendar, set the date and time, confirm and schedule. If you don’t see it, the rollout probably hasn’t reached your account yet.

If you’re on Android, or the icon is missing, you have two reliable workarounds:

• Use x.com in a mobile browser. Log in, open the composer and use the same calendar icon. If the page shows a cut-down layout, switch your browser to its desktop site option.
• Write the text in your notes app, schedule on a computer. Paste it into the web composer when you’re at a desktop.

Do you need Premium?

Based on what’s documented, no. X’s help center doesn’t list scheduling in the standard web composer among Premium features, and testing reports describe it as free for all accounts. The paid piece is X Pro, the multi-column dashboard formerly known as TweetDeck. According to MacRumors, X moved X Pro behind the Premium+ plan in March 2026.

X Pro does have its own scheduler. Per X’s help center, you click Schedule post, select the date and time, and click Schedule post at [date/time]. A scheduled column lets you view and edit what’s queued. Two details from that page are worth knowing: X Pro doesn’t support scheduled Direct Messages, and in a corporate setup, scheduled posts for connected accounts are visible to anyone with access.

One more catch: X’s edit rules say posts made through third-party tools or X Pro can’t be edited. If a typo would be costly, see our guide to editing a post on X before choosing where to schedule it.

Where to find your scheduled posts

In the web composer, click Post, then Unsent posts. You’ll see two tabs:

• Drafts: posts you saved without picking a time. They won’t publish on their own.
• Scheduled: posts with a publish time, listed with that time.

Mixing these up is the number one reason people think scheduled posts are “not showing.” If you closed the composer and chose to save the post, it likely went to Drafts. Open the draft and set a time on it to make it a scheduled post.

If you use the ads composer, X’s help center says to open the Posts tab, switch the drop-down from “Promoted” to “Scheduled,” and manage everything there. Note that scheduled posts only appear in the campaign dashboard once they’ve gone live.

Edit, reschedule or delete a scheduled post

Open Unsent posts, go to Scheduled and click the post. It opens in the composer, where you can change the text, media or time and save it again. To remove it, delete it from the same list.

X’s help center confirms the same options in the ads composer: hover over the post, click the three dots, then choose Edit or Delete. It adds that when a scheduled post goes live, it carries the timestamp of the time you set and the post ID doesn’t change.

One practical point: editing a scheduled post before it publishes is different from the Premium-only Edit feature that works on live posts. Before it’s live, it’s just a saved item you can reopen. After it’s live, the normal rules apply, including the one-hour window and the Premium requirement.

What you can schedule

X’s help center confirms that scheduled posts can include copy, photos, videos and cards in its ads composer, and X Pro lets you attach an image or video. For threads, polls and replies in the standard composer, X doesn’t document the rules, and reports conflict. The safe approach is to test: build the post, open the calendar, and if the schedule option is missing or greyed out, that format can’t be scheduled on your account.

For multi-post threads, the safest workflow is to draft the whole thing first and publish it when you can be present. Our guide to writing a thread on X covers that, and polls need a careful check before they go live because they can’t be edited later.

Time zones and timing

X’s help center doesn’t publish time zone rules for the standard composer. Reports say the picker uses your account’s time zone, but check the time shown on the confirmation screen and in your Scheduled list rather than assuming. If you travel or manage an account for another region, do a test post scheduled a few minutes ahead the first time.

When to schedule matters as much as how. There’s no universal best hour, and our guide to the best time to post on X shows how to find yours from your own analytics. Then use the scheduler so those slots no longer depend on you being awake.

Why a scheduled post didn’t appear or publish

X doesn’t publish a troubleshooting list for this, so work through the likely causes in order:

Symptom	Likely cause	What to do
Can’t find the post	It’s in Drafts, not Scheduled	Open Unsent posts, check both tabs
No calendar icon	Feature not rolled out to your app, or you’re in a view without it	Update the app, or use x.com on a computer
Post missing in the ads dashboard	It only appears there once live	Check the Posts tab, Scheduled view
Went out at the wrong hour	Date, AM/PM or time zone mix-up	Reopen the scheduled item and verify the time
Didn’t publish at all	Account restricted, locked or hitting limits	Check your account status and X’s limits
Post published but little reach	Timing or content, not the scheduler	See how the algorithm works

If a post did not appear under Scheduled and isn’t live on your profile, assume it didn’t save. Re-create it, and confirm it shows in the list before you close the tab.

A simple weekly scheduling routine

Scheduling works best as a small batch, not an all-day project.

Day	Task	Time
Sunday or Monday	Review last week’s analytics and pick 3–5 posts for the week	20 min
Same session	Write and schedule them in your best time slots	30–40 min
Midweek	Check the Scheduled tab for gaps or clashes	5 min
Every posting day	Be around for 15–30 minutes after a post goes live to reply	15–30 min
Friday	Note which scheduled posts did best, and adjust next week	10 min

Keep a few slots empty for news and replies. Scheduled posts are for content that doesn’t age, not for reacting to events. Pause the queue if something major happens that makes a pre-written post look tone-deaf.

Pairing scheduled posts with a stronger start

A scheduled post lands in a feed at a time you chose, but it still starts with whatever attention your account already has. If you have an important post going out at a peak slot, some people pair it with added views or likes to give it a stronger start. It’s optional, and it doesn’t replace a good post or a regular posting habit.

Third-party scheduling tools

Third-party scheduling tools exist and can add features like calendars and approval flows. If you use one, only connect it through X’s own authorization screen, and never share your password with any tool or person. Remember that actions from every connected app count toward the same limits, and posts made through third-party tools can’t be edited with X’s Edit feature.

Key takeaways

• On the web: Post, calendar icon, date and time, Confirm, Schedule.
• On iPhone, X began rolling out scheduling in September 2026; Android had not shown it in reported versions.
• Find queued posts under Unsent posts, Scheduled tab. Drafts are a different tab and won’t publish.
• Standard scheduling isn’t documented as a Premium feature; X Pro and its scheduler need Premium+.
• Check dates, AM/PM and time zone, and be online after posting to reply.
