Try parse with locale options like this: import { parse, isValid, format } from ‘date-fns’; import { enGB } from ‘date-fns/locale’; const parsedDate = parse(’29/10/1989′, ‘P’, new Date(), { locale: enGB }); const isValidDate = isValid(parsedDate); const formattedDate = format(parsedDate, ‘dd-MM-yyyy’);
2018-09-14T23:59:59.999Z is not the end of day computed by endOfDay(new Date());. It is 3 hours earlier. The “Z” means UTC and your local time zone has the offset to UTC -0300. By executing endOfDay you get a date value, which you can use in comparisons and other computations with other date values. It is a … Read more
As you can see, with moment lib, we need 2 steps to get the result: parse string to Date object, then format date object to string. Your code – format(new Date(“10-13-20”), ‘MM-DD-YY’) is format step, try convert a date object to a string with format template is MM-DD-YY. But your date object is not correct. … Read more

You will need to subtract the time zone offset of your local time zone from the Date instance, before you pass it to format from date-fns. For example: const dt = new Date(‘2017-12-12’); const dtDateOnly = new Date(dt.valueOf() + dt.getTimezoneOffset() * 60 * 1000); console.log(format(dtDateOnly, ‘YYYY-MM-DD’)); // Always “2017-12-12” Problem You want to handle only … Read more
How precise do you need to be? If you do need to take into account common years and leap years, and the exact difference in days between months then you’ll have to write something more advanced but for a basic and rough calculation this should do the trick: today = new Date() past = new … Read more
According to the example code in date-fns/date-fns#229 (comment), we can now use intervalToDuration to convert seconds (passed as an Interval) to a Duration, which can then simplify formatting as desired by the OP: import { intervalToDuration } from ‘date-fns’ const seconds = 10000 intervalToDuration({ start: 0, end: seconds * 1000 }) // { hours: 2, … Read more
You were almost there. This works for me: import { parseISO } from “date-fns”; import { format, utcToZonedTime } from “date-fns-tz”; const time = “2019-10-25T08:10:00Z”; const parsedTime = parseISO(time); console.log(parsedTime); // 2019-10-25T08:10:00.000Z const formatInTimeZone = (date, fmt, tz) => format(utcToZonedTime(date, tz), fmt, { timeZone: tz }); const formattedTime = formatInTimeZone(parsedTime, “yyyy-MM-dd kk:mm:ss xxx”, “UTC”); console.log(formattedTime); … Read more
