Prayer

Hello, sometimes I am unable to put on tefillin in the morning, and I am very upset because I do not know what to recite at midday. Is it possible to know what should be read at midday?

On which fast days, apart from Yom Kippur (which I know is excluded), are tefillin worn?

Is it good to light a candle on Rosh Chodesh or in honor of Rosh Chodesh? And if there is someone who is ill and he lights the candle, does that have any effect? Thank you in advance! Wonderful websit...
