Question details
The user wants to configure Microsoft Project to display specific week numbers and day numbers on the project timeline and Gantt chart.

- Product
- Microsoft Project
- Device & OS
- not provided
- Scenario
- Customizing the timeline and Gantt chart view to show specific time increments (weeks and days) counting from the project start date.
- Observed behavior
- The user needs to display specific time units, noting that modifying the Gantt Chart timescale does not automatically update the visual Timeline bar above it.
Ensure you have your Microsoft Project file open in the Gantt Chart view before adjusting the timescale settings.
Configure the Gantt Chart Timescale for Weeks and Days
Adjust the middle and bottom tiers of the Gantt chart timescale to show week and day numbers starting from the project start date.
Microsoft Project allows you to customize up to three tiers of your timescale. To display both weeks and days, you will need to utilize the Middle Tier and Bottom Tier settings.
Open your project file and ensure the Gantt Chart view is active on your screen.
Double-click the timescale bar located at the top of the Gantt Chart pane to open the Timescale dialog box.
Go to the Middle Tier tab. Select 'Weeks' as the unit, set Count to 1, and choose the label format 'Week 1, Week 2, ... (From Start)'.
Switch to the Bottom Tier tab. Select 'Days' as the unit, set Count to 1, and select the label format 'D1, D2, D3, ... (From Start)'.
Click OK to save and apply the new timescale format to your Gantt chart view.

Customize the Visual Timeline Bar
Configure the Timeline bar independently, as it does not inherit settings from the Gantt chart timescale.

Frequently Asked Questions
Why doesn't my Timeline bar change when I update the Gantt chart timescale?
In Microsoft Project, the Timeline bar and the Gantt chart timescale operate independently. Updating the timescale on the Gantt chart will not automatically change the visual Timeline at the top. You must configure the Timeline bar separately by clicking on it and using the Timeline Format tab on the ribbon.
How do I show continuous week numbers instead of specific calendar dates?
Double-click the timescale bar, select the Middle Tier tab, set your unit to 'Weeks', and choose the label format 'Week 1, Week 2, ... (From Start)'. This will display continuous weekly numbering starting exactly from your project's kickoff date rather than calendar dates.
Can I show both weeks and days simultaneously on the Gantt chart?
Yes. You can use a multi-tier timescale to achieve this. Set the Middle Tier to display 'Weeks' and the Bottom Tier to display 'Days' within the Timescale settings dialog box. This allows you to view broader weekly summaries along with specific daily details at the same time.
