Dates and Times Showing Wrong in My App
Dates and times in your app show incorrect values. Events show the wrong day, timestamps are off by several hours, or the same date shows differently in different parts of the app. This is confusing for users and can break time-sensitive features like bookings or deadlines.
Common Causes
- Timezone handling ā server stores UTC but the app displays UTC instead of the user's local time
- JavaScript Date parsing inconsistencies across browsers
- Database stores dates as strings instead of proper date types
- Date formatting differs between server and client
- Daylight saving time not accounted for
How to Fix It
- Check if dates are stored as UTC in the database (they should be)
- Make sure the frontend converts UTC dates to the user's local timezone for display
- Use a date library (date-fns, dayjs, luxon) instead of raw JavaScript Date
- Be consistent with date formats throughout the app
- Test with users in different timezones to verify correct display

Get HelpFrequently Asked Questions
Events show one day off for some users. Why?
This is almost always a timezone issue. Dates stored as UTC might display as the previous or next day depending on the user's timezone.
Can a developer fix all the date issues at once?
Yes. A developer can standardize date storage (UTC), add proper timezone conversion for display, and use a consistent date formatting library throughout the app.
