Plan your life in full colour with this tasty A4 art calendar that is designed for bringing a little spark of joy to your plans.

Each monthly calendar page has a dated grid from Monday to Sunday, with space to jot down your appointments, events or birthdays. It also includes week numbers, moon phases, UK & US holidays, notable dates, and a mini overview of the month ahead.

Nice thick paper means lots of writing with no bleeding through pages.

Hang this colourful piece of paper stationery above your desk or on your kitchen wall - it has a hook built in.

If you’re looking for a calendar to add style and a colourful vibe into your home, office, studio or dorm room, this 2025 A4 calendar is the one.

Optional: add a pack of corner stickers to level up your planning in 2025.

As always, designed and printed in the UK on 100% recycled paper.
