Royal Hats 
Does anyone know when Royal Ascot 2018 (particularly ladies day) is – as two websites are showing two different dates. 14-18 or 19-23 June 18? Thanks
While the official Ascot website is only posting dates for 2017, several reliable racing sources all cite the dates for Royal Ascot 2018 as I have published above. Ladies’ Day is always Thursday.
Thank you.
Royal Ascot is a week later in 2017, June 20-24 https://www.ascot.co.uk/Royal-Ascot
Thanks, Marlene. Correction made!
