If you do something with someone else, you have Cohorts. But if you work alone, you are logically a single Hort.
If you reschedule something to a later date, you are Postponing it. However, if you want to reschedule something to an earlier date, logically you must be Preponing it. This word has reportedly been adopted by English speakers in India, and comes from the Latin praepono.
Please direct any complaints to whoever keeps putting Latin into English.
