Date & Date Time Fields

This article explains how the Date and Date & Time fields work in the Sintel Apps Designer and how to configure their available options.

These fields are used when a user must select a calendar date, with or without a time value. When added to a form, they create a corresponding Date or DateTime column in the underlying SharePoint list.

What Is a Date Field?

A Date (Date Only) field allows users to select a calendar date without specifying a time.

It is commonly used for:

• Start dates
• End dates
• Review dates
• Submission deadlines
• Effective dates

Use Date when time is not relevant to the process.

What Is a Date & Time Field?

A Date & Time field allows users to select both a calendar date and a specific time

It is commonly used for:

• Meeting scheduling
• Incident timestamps
• Event start times
• Escalation deadlines
• Time-sensitive approvals

Use Date & Time when accuracy to the hour or minute is required.

Properties

When selecting either field in the Layout tab, the following properties are available:

Title – The label displayed on the form.

Type – Date Only (for date field) or Date Time (for date & time field)

Required – If enabled, users must enter a value before saving or submitting.

Unique – Prevents duplicate values (rarely used for date fields).

Default Value – Controls what value is pre-selected when the form loads.

Available options:

• From SharePoint – Uses the default configured at list level
• Custom – Manually enter a default date (or date & time)
• Query Parameter – Pre-populate from a URL parameter

Placeholder – Text shown before a value is selected (e.g. “Select a date”).

Behaviour Settings –  The State setting controls how the field behaves.

Available options:

• Inherit from section – Follows the section’s behaviour
• Mandatory – Always required
• Optional – Not required
• Read-only – Cannot be edited by users

State can also be modified dynamically using Logic rules.

Label Settings: You can configure: Label text, Label position, Tooltip

Tooltips are helpful when selection rules need clarification (e.g. “Must be after today”).

Using Date Fields in Logic

Date and Date & Time fields are commonly used to:

• Compare two dates
• Validate date ranges
• Trigger workflow steps
• Calculate deadlines
• Display validation messages

Examples:

If End Date is earlier than Start Date, display a validation error.

or

If Incident Time is more than 24 hours old, escalate automatically.
