Every year, we receive the Torah anew as we celebrate the festival of Shovuos. The name ‘Shovuos’ means weeks, as the holiday marks five weeks since Pesach. It’s at the end of this period that we accept the Torah all over again and rejoice in it. It’s important to hear the Ten Commandments read in shul- this mitzvah applies to all, including men, women and children, so you should try to be at your nearest shul tomorrow to hear this. Additionally, it is customary to stay up all night tonight learning Torah, to make up for the fact that the Israelites overslept when they were supposed to receive it.
Like on Shabbes, all forms of work are forbidden until after nightfall on Thursday. This includes writing, driving, shopping, and using electricity. Cooking and carrying items needed for the yontiff are permissible under certain circumstances. Please consult Chabad.org for actual guidelines.
In London, holiday candles should be lit at 8:48 PM today, and after 10:18 PM tomorrow (from a pre-existing flame). The yontiff ends after 10:19 PM on Thursday. While lighting candles, please keep in mind Chaim Elozor ben Baila, Moshe ben Hadasa, Moshe ben Genya, Chashachana bas Bryna and Tova bas Taloob for a refuah shleimah. Thank you, and gut Yontiff!
