To search WhatsApp messages by date, follow these steps for both Android and iOS devices with the latest versions supporting this feature:

  1. Open WhatsApp and navigate to the chat window where you want to search for a message by date.
  2. Tap on the search bar (usually at the top of the chat window).
  3. Look for a calendar icon in the right corner of the search bar.
  4. Tap on the calendar icon to access the date picker.
  5. Choose the year and month you want to search for.
  6. Tap on 'Jump to date' to navigate to the specific messages from the selected date.

For iOS users, the calendar icon may be found when tapping on the name of the recipient (or the chat head) before searching. For Android users, the calendar icon is typically in the search bar.

Please note that this feature may not be available to all users yet, as it was initially released to beta testers and may take time to roll out to all users.
