भानुसप्तमी*

saptamI tithi on a Sunday is as sacred as a solar eclipse. Particularly good for worshipping Surya. Today is even more auspicious, as it is associated with revatI star.

अमावस्या तु सोमेन सप्तमी भानुना सह। चतुर्थी भूमिपुत्रेण सोमपुत्रेण चाष्टमी। चतस्रस्तिथयस्त्वेताः सूर्यग्रहणसन्निभाः॥
