Probably due to using latest versions of date-fns. Which is not supported by /pickers v3.

[ronaksonigara]

Tried using different versions but it still not working. Kindly help me with the version.

@ronaksonigara I changed version @date-io/date-fns on 1.3.13 and it is work.

Thanks it's working

[oliviertassinari]

I believe the root issue was solved in the work-in-progress v4 of the pickers component by moving @date-io as an internal dependency. cc @dmtrKovalenko for confirmation. I'm not sure what can do about it in the meantime 🤔

[dmtrKovalenko]

https://codesandbox.io/s/material-demo-bqjuv Working version. @date-io/date-fns should be locked to v1.x

[oliviertassinari]

So we can either (1.) start the upgrade to v4-alpha or (2.) lock the version in https://github.com/mui-org/material-ui/blob/8d0a7e19446849b8d5992b27ee3ee48b76005596/docs/src/modules/utils/helpers.js#L98-L110 ?

I think we should not propagate alpha version, because we are still planning breaking changes. Lets wait to the first beta

I'm having an issue with date pickers at the moment where it's showing me 1 day behind the selected date.

The displayed date in Material UI Pickers is 1 day behind the selected date:

I selected 25th, the value in formik is 25th but the value displayed on the form is 24th.

  "@date-io/date-fns": "^1.3.13",
  "date-fns": "^2.9.0",

import DateFnsUtils from '@date-io/date-fns';
import { MuiPickersUtilsProvider, DatePicker } from '@material-ui/pickers';
import { format, addDays } from 'date-fns';

<MuiPickersUtilsProvider utils={DateFnsUtils}>
    <FastField
       as={DatePicker}
       variant="inline"
       disableToolbar
       name="startTime"
       format="PPP"
       onChange={date => {
         console.log(format(date, 'yyyy-MM-dd'));
         setFieldValue('startTime', format(date, 'yyyy-MM-dd'));
       }}
       value={values.startTime}
   />
</MuiPickersUtilsProvider>

Could it be a dependency versioning issue?

[dmtrKovalenko]

@simkessy, no it is definitely not version issue

[simkessy]

Any idea what the issue could be here?

[oliviertassinari]

Per the codesandbox description:

https://github.com/mui-org/material-ui/blob/master/docs/src/pages/components/pickers/MaterialUIPickers.js

I believe this issue should be moved to the main repository and appears to be a duplicate of #19438.
