Adding the word please makes the phrase softer and more polite. This is especially useful in business, academic, and customer-facing communication.

This version sounds courteous while still being direct. It is a great choice for emails, event reminders, and announcements where professionalism matters.
Common Mistakes to Avoid
Even though the phrase is easy to use, a few mistakes show up often.
1. Using it too many times in one text
If you repeat mark your calendar too often, the writing can feel forced. Use it once or twice and vary the wording after that.
2. Confusing singular and plural
Use “calendar” for one person and “calendars” for a group.
3. Making the sentence too long
The phrase works best when the date is clear and easy to notice. Avoid burying it inside a long paragraph.
4. Overloading the message with reminders
A single strong reminder is usually more effective than multiple repeated ones.

- Put the date near the phrase.
