NaPoWriMo 30 – something that happens every year

So here it comes again,
my Beltane birthday,
when spring and summer touch,
and the goddess throws on
her greenest gown
and whirls into the dance.
My fire-crackle, spark fly
birthday. Here it comes –
my sakura birthday,
pink foaming cherry flowers
floating and flying,
and look out – it’s my
apple blossom birthday,
when the secret fruit trees
flower in the hedgerow.
Here it is – my hawthorn birthday,
banks frothing with cow parsley –
sing it loud, it’s my
chocolate cake birthday,
my candles and cards
and morning cuddles birthday.
Watch out, it’s here,
my last day of April,
wash your face in dew,
dream of true love,
wake me early in the morning,
jump through the fire with me
birthday. It’s today.

It’s the last day of April – the last day of NaPoWriMo – and my birthday! And today’s prompt is to write about something that keeps on happening. So what better subject?
