Hanuman Jayanti is celebrated on Sunday, 20th of April 2008
Sri Hanuman believed and stated in the 'Ram-Charit-Maanas' (penned by Goswami Tulsidas):

Kahe Hanuman vipattee Prabhu soyee
Jab kabhee Sumiran bhajan na hoyee

Hanuman believes and states that,
it is a misfortune when one forgets to remember the Lord, and take His Name.

So my dear friends whatever trials and tribulations we are going through are nothing. According to Hanuman we have a misfortune, only if you and I forget to think of the Lord and/or sing His praise.
Let us remember to do the Hanuman Chalisa preferably 11 times, if not, at least once on Hanuman's day. It is believed that Sri Ram is forever indebted to Hanuman because of the latter's service. And since Hanuman wanted nothing in return, Sri Ram would have to grant the wishes of Hanuman, if he intercedes for us, His devotees.
