Post it on twitter or Facebook or wherever you hang out with the hashtag #fallbackintime then sit back RT and or share all the posts you see and watch it trend across the internet
Here is my pic from last year to give you the idea. In addition to the hashtag, if you are into social media, you can tag the historical romance networks too:
FB: (@HistoricalRomanceNetwork) https://www.facebook.com/historicalromancenetworkTwitter: (@histromnet) https://twitter.com/histromnetTumblr: http://historicalromancenet.tumblr.com/
While Europe have already done their clocks, that is no reason not to join in if you love historicals. The more the merrier for this celebration.
Above is the one I did last year so you can see what I mean (I'll be doing a new one for this year). You don't need to add text to the photo, but you do need to put the hashtag in the post to have it show up on Social Media and see it shared around the world.
Join in by retweeting and sharing etc. if you don't want to do a picture of your own. See you on Sunday.
