st.column_config.DateColumn

Configure a date column in st.dataframe or st.data_editor.

This is the default column type for date values. This command needs to be used in the column_config parameter of st.dataframe or st.data_editor. When used with st.data_editor, editing will be enabled with a date picker widget.

Function signature[source]
st.column_config.DateColumn(label=None, *, width=None, help=None, disabled=None, required=None, default=None, format=None, min_value=None, max_value=None, step=None)
Parameters
label (str or None)	The label shown at the top of the column. If None (default), the column name is used.
width ("small", "medium", "large", or None)	The display width of the column. Can be one of "small", "medium", or "large". If None (default), the column will be sized to fit the cell contents.
help (str or None)	An optional tooltip that gets displayed when hovering over the column label.
disabled (bool or None)	Whether editing should be disabled for this column. Defaults to False.
required (bool or None)	Whether edited cells in the column need to have a value. If True, an edited cell can only be submitted if it has a value other than None. Defaults to False.
default (datetime.date or None)	Specifies the default value in this column when a new row is added by the user.
format (str or None)	A momentJS format string controlling how times are displayed. See momentJS docs for available formats. If None (default), uses `YYYY-MM-DD`. Number formatting from `column_config` always takes precedence over number formatting from `pandas.Styler`.
min_value (datetime.date or None)	The minimum date that can be entered. If None (default), there will be no minimum.
max_value (datetime.date or None)	The maximum date that can be entered. If None (default), there will be no maximum.
step (int or None)	The stepping interval in days. If None (default), the step will be 1 day.

st.data_editor(
    data_df,
    column_config={
        "birthday": st.column_config.DateColumn(
            "Birthday",
            min_value=date(1900, 1, 1),
            max_value=date(2005, 1, 1),
            format="DD.MM.YYYY",
            step=1,
        ),
    },
    hide_index=True,
