Need help: Core practices and blessed days in Islam

Assalamu Alaykum everyone, I’m reaching out because I took my shahada a little over a year ago, and I’m still trying to grasp all the small yet important parts of the deen. I know about Ramadan and Eid al-Adha, but I keep discovering other beautiful Sunnah practices almost by accident. For instance, I recently came across a mention of fasting on Ashura while scrolling online, and it made me realize how much I’m missing. Also, my mother-in-law always says 'Bismillah' when she steps into the house, and I want to understand more of these habits and when to use them. I’d love to know about essential daily du'as, blessed days for extra worship, and other routines you grew up with. Please share any practical tips-they would mean so much to me as I try to build my life as a Muslim. Jazakum Allahu khayran!
