Definition:

Misdate: To incorrectly write the date on a document or any other item.

Examples:

• She misdated the check, causing it to be returned by the bank.
• The letter was misdated, making it seem like it was sent a week earlier than it actually was.

Explanation: Misdate means to make a mistake while writing the date on something. For instance, if someone writes the wrong year or month on a check, it can cause problems with the bank. Similarly, if a letter is misdated, it can create confusion about when it was actually sent. These examples illustrate how misdating can lead to errors and misunderstandings.
