Amaavas

Amaavas is the no-moon night: the last tithi of the dark fortnight, when the moon is fully hidden and the sky turns darkest before the cycle begins again with the new bright fortnight. Every month brings one, and the calendar marks it plainly rather than as a festival in its own right, because it isn't one — it is a marker of where the moon stands, the same way Poonam marks the full moon fifteen days later. A few Amaavas nights carry an extra name because something else happened to fall on them (a new year, the end of an Adhik Maas, a particular Ghata), and those are noted separately when it matters.

In the wider Hindu calendar Amaavas is often treated as a day for remembering ancestors and for stillness rather than celebration, and many people keep a lighter or more contemplative day around it.

For a Pushtimarg Vaishnav, Amaavas has no vrat or seva rule attached to it the way an Ekadashi does — it is simply useful to know, because it anchors where you are in the month. Reading a Pushtimarg calendar without knowing Amaavas and Poonam is like reading a clock without knowing which numbers are twelve and six: everything else is described relative to them.

If there is a bhav worth carrying into an Amaavas night, it is a quiet one: the moon giving nothing back is not the moon failing, it is the moon on its way to fullness again. A devotee can hold the same patience toward their own sadhana — a dry or dark stretch is not the end of the story, only a phase of it, with the bright half already on its way.
