Components

Pickers — rich popups with full interaction

These are the main attraction. Calendar popups, scrolling time panels, range selection with hover highlighting — everything you'd expect from a production date/time picker.

Component	Description	Streamlit equivalent
date_picker	Calendar popup with format control, one-tap, ISO week	st.date_input
date_range_picker	Dual-calendar popup for date ranges, hover range	st.date_input (range mode)
time_picker	Time picker with scrolling panel, AM/PM	st.time_input
time_range_picker	Time range picker with dual panels	--

Inputs — simple keyboard-only entry

Lightweight alternatives with no popup. Users navigate date segments with arrow keys and typing — useful for compact forms where a full picker would be overkill.

Component	Description	Streamlit equivalent
date_input	Keyboard-only date input (no popup)	st.date_input
date_range_input	Keyboard-only date range input (no popup)	st.date_input (range mode)

All components are MIT licensed (RSuite is fully open-source).

Quick start

import streamlit as st
from datetime import date, time, timedelta
from st_rsuite import (
    date_picker, date_range_picker, time_picker,
    time_range_picker, date_input, date_range_input,
)

# ── Pickers — the star of the show ──────────────────────────────────────────

# Calendar popup with one-tap selection
d = date_picker(label="Pick a date", value=date.today(), one_tap=True, key="my_dp")

# Dual-calendar range picker with week hover highlighting
start, end = date_range_picker(
    label="Trip dates",
    value=(date.today(), date.today() + timedelta(days=7)),
    hover_range="week",
    key="my_drp",
)

# Time picker with AM/PM
t = time_picker(
    label="Pick a time", value=time(9, 30),
    format="hh:mm aa", show_meridiem=True, key="my_tp",
)

# Time range — great for scheduling
t_start, t_end = time_range_picker(
    label="Shift hours",
    value=(time(9, 0), time(17, 0)),
    key="my_trp",
)

# ── Inputs — simple keyboard-only entry (no popups) ─────────────────────────

d2 = date_input(label="Type a date", value=date.today(), key="my_di")

start, end = date_range_input(
    label="Date range",

Inputs

Simple keyboard-only components — no popups, designed for compact quick-entry scenarios.

date_input

date_input(
    label="",
    value=None,           # date object or YYYY-MM-DD string
    format="yyyy-MM-dd",  # Unicode date format tokens
    size="md",            # 'lg' | 'md' | 'sm' | 'xs'
    placeholder=None,
    disabled=False,
    locale=None,          # e.g. 'ja_JP', 'zh_CN', 'es_ES'
    on_change=None,
    key=None,
) -> date | None

date_range_input

date_range_input(
    label="",
    value=None,           # tuple of (date, date) or (str, str)
    format="yyyy-MM-dd",
    character=" ~ ",      # separator between start and end
    size="md",
    placeholder=None,
    disabled=False,
    locale=None,          # e.g. 'ja_JP', 'zh_CN', 'es_ES'
    on_change=None,
    key=None,
) -> tuple[date | None, date | None]

Locale / i18n

All components accept a locale parameter to switch calendar labels, month/day names, and button text to the target language. RSuite ships 29 locales out of the box.

When locale is not set, the component automatically detects the browser's language (navigator.language) and uses the closest matching RSuite locale. For example, a browser set to Japanese will show Japanese calendar labels without any code changes.

from st_rsuite import date_picker

# Japanese
date_picker(label="日付を選択", locale="ja_JP", one_tap=True, key="jp")

# Chinese (Simplified)
date_picker(label="选择日期", locale="zh_CN", one_tap=True, key="cn")

# Spanish
date_picker(label="Elegir fecha", locale="es_ES", one_tap=True, key="es")

Available locales: ar_EG, ca_ES, cs_CZ, da_DK, de_DE, en_GB, en_US, es_AR, es_ES, fa_IR, fi_FI, fr_FR, gu_IN, hu_HU, it_IT, ja_JP, kk_KZ, ko_KR, ne_NP, nl_NL, pl_PL, pt_BR, ru_RU, sv_SE, th_TH, tr_TR, uk_UA, zh_CN, zh_TW
