You can configure whether calendar reports use field styles from the tables or report sources that they are based on. ### Before you begin Role required: admin ### About this task By default, field styles in the Task \[task\] table are applied to calendar reports. If calendar reports are configured to use field styles from their tables or report sources, these field styles override the Task table styles. **Note:** Calendar highlighting only applies to Core UI reports, not to Platform Analytics experience data visualizations. ### Procedure 1. In the filter navigator, enter: `sys_properties.list` 2. Select the **glide.ui.report.extend\_calendar\_choices** property to specify which field styles are used during calendar highlighting. - If `false`, calendar reports will use only styles from the Task table when determining options for calendar highlighting. For example, a calendar report on the Change Request \[change\_request\] table will only use styles from the Task \[task\] table instead of styles from a the combination of the two tables. - If `True`, calendar reports will use field styles from the table that the calendar report is based on. 3.

You can also configure the maximum number of events that appear in this pop-up window. When this maximum is exceeded, a **+ many** link appears, which opens a list of events instead of a pop-up window. You can configure these settings for the following calendar views: - A calendar day when calendar is in month or year view - The top 'full day' section of a calendar day when a calendar is in day or week view ### Procedure 1. In the navigation filter, enter `sys_properties.list`. 2. Configure the **glide.report.calendar.max\_events\_displayed\_per\_cell** and **glide.report.calendar.max\_more\_events\_per\_day** properties. 3. Click **Update**. **Related topics** [Add a system property](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/platform-administration/t_AddAPropertyUsingSysPropsList.md) ## Change the day that calendar weeks start on By default, weeks for calendar reports start on Sunday. You can add a system property to start weeks on Sunday or another day instead. ### Before you begin Role required: admin The **glide.ui.date\_format.first\_day\_of\_week** system property modifies the generated date/time value used in the query and sets the start day of the week in the rendered calender. **Note:** **glide.ui.filter.first\_day\_of\_week** must also be set to the same value as **glide.ui.date\_format.first\_day\_of\_week** for the set day to display properly. If you change the **glide.ui.filter.first\_day\_of\_week** property after collecting Performance Analytics score data, you won't be able to view the scores for weekly indicators. To access them, you must [collect scores](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/now-intelligence/performance-analytics/c_ClctData.md) again. ### Procedure 1. Add the **glide.ui.date\_format.first\_day\_of\_week** system property. 2. Set one of the following integer values.
**Start weeks on Sunday** Set **Value** to `1`
**Start weeks on Monday** Set **Value** to `2`
**Start weeks on Tuesday** Set **Value** to `3`
**Start weeks on Wednesday** Set **Value** to `4`
**Start weeks on Thursday** Set **Value** to `5`
**Start weeks on Friday** Set **Value** to `6`
**Start weeks on Saturday** Set **Value** to `7`
**Note:** Only Sunday and Monday are explicitly supported. 3. Click **Submit**. ### What to do next Configure the system property **glide.db.week\_numbering** to specify how weeks are calculated.
