can my mom order concert tickets for a concert that shell be attending after her one year mourning is over and the concert is after the year so can she order the tickets before hand? and can we attend the concert during the 10 days between rosh hashana and yom kippur ?
Shalom, Thank you for your question. One may order the tickets for a concert that will be taking place after the year of mourning even before the year has ended. As to attending the concert during the 10 days between Rosh HaShona and Yom Kippur – it will depend on what type of concert it is, and your individual level of service of G-d. Obviously if the concert involves things opposed to holiness and Jewish values, it should be avoided all year long. And if it is a concert to encourage religious growth (such as evening of Torah with religious music) then it is a great mitzvah to attend. But if it is neither here nor there (such a classical music concert), it will depend on “where you are holding”. If you would be otherwise immersed in the saying of psalms and doing good deeds – you should avoid the concert during these special days that are set aside to come close to Hashem. But if going to the concert is going to take you away from doing other sins, or even just wasting your time, and it will enhance your state of mind and happiness, perhaps it is a good thing to go. Only you can be the judge of the best way to use these precious days to come closer to Hashem in the best way for you – recalling always that one's spiritual growth must be paced according to one's true level of advancement, without trying to jump to far ahead of where one is presently holding. Blessings.
