To search WhatsApp conversations on an Android device using the search by date feature, follow these steps:

  1. Open WhatsApp on your Android smartphone.
  2. Navigate to the individual or group chat where you want to perform the search.
  3. Tap on either the contact or group name to access the conversation details.
  4. Locate and tap the search button within the conversation details.
  5. Once in the search interface, tap the calendar icon located in the upper right corner of the search bar.
  6. Select the specific date you're interested in by choosing the appropriate month and day.
  7. After selecting the date, press OK; WhatsApp will display messages from that chosen date.

Please note that currently, WhatsApp supports searching for messages on a single specified date, not a date range. If you've recently updated your WhatsApp application and haven't yet received this feature, it could be due to a phased rollout, meaning it takes time for the feature to become available to all users.
