Shvat 5781

Shvat: let’s get it all over with in one day!

There are families with lots of birthdays in the same month. Or who have yahrzeits (anniversaries of deaths) close to public holidays. Or institutions or countries who have lots of historic days. These often get combined and turned into one day marking many events.
This phenomenon was reflected in a light-hearted activity in which people received the names of the Jewish holidays and were asked to decide when in the year to mark them. A creative suggestion was to take all the sad days (9 Av, holocaust day, memorial day for Israeli soldiers, minor fasts) and put them all together in one week in the winter – same idea, let’s get everything over with in one sad week and then move on.
Where this really happens, of course, is 9 Av itself which commemorates everything from the spies returning to Moses with a bad report about the Land of Israel to the bombing of the community center in Buenos Aires. No doubt some of the many events associated with this day happened on or close to 9 Av but others were attached to it for convenience.
The impulse is an understandable one. Having too many memorial or celebratory days diminishes the impact of each one. One day that marks many events makes it stronger and more attractive. We can all have fatigue from over-celebrating/commemorating.

An example of where a holiday is in the process of gathering extra meanings is Tu B’Shvat. Tu B’Shvat marks the point when the ground has become soaked with the rains of the new year, causing the liquid to start rising in the trees, which means that the trees can begin to give fruit (Rashi) or the moment that trees get their life source from the water of the new year rather than relying on water from the previous year (Jerusalem Talmud). The day has halachic (Jewish legal) significance in terms of tithes and allowing fruit to be eaten that has grown for three years.

There are other new years for other agricultural events. For example, 1 Tishrei (Rosh Hashana) is, every seven years, the beginning for the sabbatical year when fields lie unused. It is also the day for calculating tax on vegetables and grains. And 1 Elul (a month before Rosh Hashana) is the day for calculating the tithing of cattle. Yet, for most Jews, Tu B’Shvat (15 Shvat) is the day for all things Jewish and land-connected. Just as 9 Av has become the catch-all day for sad events, 15 Shvat has become the across-the-board day for thinking about nature.
Customs for the day include:

 Try something new this Tu B’Shvat, for yourself and for those around you.

Jewish environmental activism and education

As the world becomes more and more aware of how our actions threaten to destroy the environment, a new element has been added to 15 Shvat and it has become a day for education and activism about issues such as pollution, global warming, and wasting of resources.
