A React-Native datetime-picker for Android and iOS
A declarative cross-platform react-native date and time picker.
This library exposes a cross-platform interface for showing the native date-picker and time-picker inside a modal, providing a unified user and developer experience.
Under the hood, this library is using @react-native-community/datetimepicker.
If your project is not using Expo, install the library and the community date/time picker using npm or yarn:
# using npm $ npm i react-native-modal-datetime-picker @react-native-community/datetimepicker # using yarn $ yarn add react-native-modal-datetime-picker @react-native-community/datetimepicker
Please notice that the @react-native-community/datetimepicker package is a native module so it might require manual linking.
If your project is using Expo, install the library and the community date/time picker using the Expo CLI:
npx expo install react-native-modal-datetime-picker @react-native-community/datetimepicker
To ensure the picker theme respects the device theme, you should also configure the appearance styles in your app.json this way:
{
"expo": {
"userInterfaceStyle": "automatic"
}
}Refer to the Appearance documentation on Expo for more info.
import React, { useState } from "react"; import { Button, View } from "react-native"; import DateTimePickerModal from "react-native-modal-datetime-picker"; const Example = () => { const [isDatePickerVisible, setDatePickerVisibility] = useState(false); const showDatePicker = () => { setDatePickerVisibility(true); }; const hideDatePicker = () => { setDatePickerVisibility(false); }; const handleConfirm = (date) => { console.warn("A date has been picked: ", date); hideDatePicker(); }; return ( <View> <Button title="Show Date Picker" onPress={showDatePicker} /> <DateTimePickerModal isVisible={isDatePickerVisible} mode="date" onConfirm={handleConfirm} onCancel={hideDatePicker} /> </View> ); }; export default Example;
👉 Please notice that all the @react-native-community/react-native-datetimepicker props are supported as well!

Under the hood react-native-modal-datetime-picker uses @react-native-community/datetimepicker.
If you're experiencing issues, try swapping react-native-datetime-picker with @react-native-community/datetimepicker. If the issue persists, check if it has already been reported as a an issue or check the other FAQs.
Set the mode prop to time.
You can also display both the datepicker and the timepicker in one step by setting the mode prop to datetime.
Please make sure you're using the date props (and not the value one).
Yes!
You can set the display prop (that we'll pass down to react-native-datetimepicker) to inline to use the new iOS 14 picker.
Please notice that you should probably avoid using this new style with a time-only picker (so with
modeset totime) because it doesn't suit well this use case.
This seems to be a known issue of the @react-native-community/datetimepicker. Please see this thread for a couple of workarounds. The solution, as described in this reply is hiding the modal, before doing anything else.
The most common approach for solving this issue when using an Input is:
Input with a "Pressable"/Button (TouchableWithoutFeedback/TouchableOpacity + activeOpacity={1} for example)Input from being focused. You could set editable={false} too for preventing Keyboard openinghideModal() callback as a first thing inside onConfirm/onCancel callback propsconst [isVisible, setVisible] = useState(false); const [date, setDate] = useState(''); <TouchableOpacity activeOpacity={1} onPress={() => setVisible(true)}> <Input value={value} editable={false} // optional /> </TouchableOpacity> <DatePicker isVisible={isVisible} onConfirm={(date) => { setVisible(false); // <- first thing setValue(parseDate(date)); }} onCancel={() => setVisible(false)} />
You can't — @react-native-community/datetimepicker doesn't allow you to do so. That said, you can allow only "range" of dates by setting a minimum and maximum date. See below for more info.
You can use the minimumDate and maximumDate props from @react-native-community/datetimepicker.
This is more a React-Native specific question than a react-native-modal-datetime-picker one.
See issue #29 and #106 for some solutions.
The is24Hour prop is only available on Android but you can use a small hack for enabling it on iOS by setting the picker timezone to en_GB:
<DatePicker mode="time" locale="en_GB" // Use "en_GB" here date={new Date()} />
Under the hood this library is using @react-native-community/datetimepicker. You can't change the language/locale from react-native-modal-datetime-picker. Locale/language is set at the native level, on the device itself.
On iOS, you can set an automatic detection of the locale (fr_FR, en_GB, ...) depending on the user's device locale.
To do so, edit your AppDelegate.m file and add the following to didFinishLaunchingWithOptions.
// Force DatePicker locale to current language (for: 24h or 12h format, full day names etc...) NSString *currentLanguage = [[NSLocale preferredLanguages] firstObject]; [[UIDatePicker appearance] setLocale:[[NSLocale alloc]initWithLocaleIdentifier:currentLanguage]];
Please make sure you're on the latest version of react-native-modal-datetime-picker and of the @react-native-community/datetimepicker.
We already closed several iOS 14 issues that were all caused by outdated/cached versions of the community datetimepicker.
Please make sure you're on the latest version of react-native-modal-datetime-picker and of @react-native-community/datetimepicker.
Also, double-check that the picker light/dark theme is aligned with the OS one (e.g., don't "force" a theme using isDarkModeEnabled).
Unfortunately this is a know issue with React-Native on iOS. Even by using the onHide callback exposed by react-native-modal-datetime-picker you might not be able to show the (native) alert successfully. The only workaround that seems to work consistently for now is to wrap showing the alter in a setTimeout 😔:
const handleHide = () => { setTimeout(() => Alert.alert("Hello"), 0); };
See issue #512 for more info.
On iOS, clicking the "Confirm" button while the spinner is still in motion — even just slightly in motion — will cause the onConfirm callback to return the initial date instead of the picked one. This is is a long standing iOS issue (that can happen even on native app like the iOS calendar) and there's no failproof way to fix it on the JavaScript side.
See this GitHub gist for an example of how it might be solved at the native level — but keep in mind it won't work on this component until it has been merged into the official React-Native repo.

See issue #216 for a possible workaround.
