# Month picker _How to add and configure a Month picker field in the Notebook Editor._ --- ## What This Field Does A Month Picker captures a year and month only (YYYY-MM), deliberately avoiding day-level precision. It is particularly valuable for historical documentation where exact dates are unknown or meaningless — preventing the common error of inventing precision where none exists. Use it for field seasons, publication dates, approximate dates of disturbance, or any temporal data where month-level granularity is appropriate. ## Adding the Field To add this field, open the [ADD A FIELD dialog](../shared-settings/adding-a-field.md), navigate to the **DATE & TIME** tab, and click the **Month picker** card. Then click the **ADD FIELD** button in the lower right. ```{screenshot} field-types-design/month-picker-01-add-field.png :alt: Adding a Month Picker — the DATE & TIME tab in the ADD A FIELD dialog :align: right :width: 100% ``` ## Configuring the Field Click the field's **grey header bar** to expand it and see its settings. For an overview of the settings shared by all fields — including Label, Helper Text, Field ID, and the field toolbar — see [Field Identity](../shared-settings/field-identity.md) and [Field Toolbar](../shared-settings/field-toolbar.md). Give the field a meaningful Label, review the auto-populated Field ID, and add any desired Helper Text. ```{screenshot} field-types-design/month-picker-02-configured.png :alt: Month Picker configuration in the {{Notebook}} Editor :align: right :width: 100% ``` ### Shared Field Options Configure any of the shared field options as needed. For settings shared across all field types — including Required, Annotation, Uncertainty, Conditions, Copy value to new records, and Display in child records — see [Field Options](../shared-settings/field-options.md). ## Tips - **Use when day-level precision is unnecessary or misleading** — "Season of fieldwork", "Month of last survey", "Approximate date of disturbance". This avoids the epistemological error of recording a specific day when only the month is known. - **Watch for Excel misinterpretation** — Excel may interpret "2024-03" as "3rd March 2024" rather than "March 2024". Always import Month Picker data as a text column to preserve the intended format. - **Consider using Uncertainty plus Annotation** to let collectors note whether the month is exact or approximate (e.g., "probably March" vs "definitely March") or specify a timeframe within the month (e.g., "late March").
