Each month at Good Tuesday, we gather all the big (and little) dates you’ll want to know about. The most important dates for your calendar and the latest social media days for your diary; so you can plan ahead, join the conversation, and never miss a reason to celebrate.
Here are the important March dates for your calendar
March is when everything starts to feel more switched on – longer evenings, hopes of less rain, and Spring is still (apparently) on schedule.
It begins with the annual World Book Day scramble: a joy for children and a late-night crafting test for parents. Followed by, Mother's Day, a chance to celebrate our mother figures while holding space for those who are missing a little more on this day.
Saint Patrick’s Day brings a welcome sea of green (and an excuse for Guinness cake), and the month ends with British Summer Time and those long-awaited lighter evenings – “basically summer,” coats still on.
Here are the key March moments to help plan your social content, and manifest brighter days.
