Triëteris

A triëteris is the Greek name for the period within 3 tropical years where the Moon phase occurs around 3 days earlier.

It corresponds to 37 synodic months,

39.9914087638034 sidereal months, 40.152246109637005 draconic months, 39.653405866893394 anomalistic months, and 1,092.6317546296311 days.

It intercalates 3 lunar years (which’s 38.910559878295196 sidereal months,

39.067050268836 draconic months, 38.5816921948152 anomalistic months,

and 1,063.101166666668 days).

Though if you intercalate a triëteris, you get a long triëteris, which’s 38 synodic months, 41.072257649311595 sidereal months,

41.237441950438004 draconic months, 40.7251195389716 anomalistic months, and 1,122.162342592594 days, and is nearly 3 synodic periods of Saturn, making it useful for calculations new/full moons in opposition/conjunction with Saturn.

The triëteris is also useful for Greek festivities on a regular basis.

A dead drop is a location used to secretly pass items between two people, without requiring them to meet.

Spies have been known to use dead drops, using various techniques to hide the items and to signal that the drop has been made. Drug dealers use this as well.

A common place is to duct tape the item to the underside of a toilet cover in a public restroom.

A signal is sometimes used as well to indicate there is something to pickup, like a pile of stones in a certain formation. After checking the drop the signal is removed.
"The dead drop is the restroom toilet at the Gulf station at the corner of Commercial Ave. and Georges Rd."

No Surprises Wedding

A "No Surprises Wedding," or NSW, is a wedding invitation designation that tells attendees that there can be no unplanned announcements, engagements, events or speeches at the wedding - all actions must be pre-approved by the couple. Anyone who performs an unapproved "surprise" will be asked to leave the wedding early.

This designation comes from Reddit, where so many stories of bad wedding behavior indicated a need to communicate expectations for the wedding behavior of attendees.
You are cordially invited to the nuptials of Brian and Tom on October 31 at noon.

Please note that this wedding is child-free (under 10) and a No Surprises Wedding (NSW). Reach out to wedding planner Sami Smith to request approvals or exceptions; please note that exceptions will be rare. Limited child care for under-10s will be available. All approvals will be noted and included in planning. Unapproved, or surprise exceptions, will result in guests being asked to leave.
