Known as National Sickie Day in the U.K., the first Monday of every February is statistically the day when most workers are likely to call in sick, according to loose surveying research.

National Sickie Day in 2025 is on Monday, February 3.

The day is a chance to take a break from work, even if you're not actually sick. Some ways to celebrate include:

• Making up an excuse: Send an email to your boss ahead of time, making up a silly or believable excuse for why you can't come to work
• Relaxing: Take a leisurely morning, watch a movie, or have a spa day at home
• Sharing memes: Share funny sick day memes or jokes on social media
• Practicing self-care: Read a book, practice yoga, or take a long bath
