To talk about plans, you need to master time markers. Here are the ones for the past-present-future axis and the most common ones for the near future.
The basic axis
Basque
English
atzo
yesterday
gaur
today
bihar
tomorrow
etzi
the day after tomorrow
etziluma / etzidamu
”the day after the day after tomorrow” (rarely used)
Three short words (atzo, gaur, bihar) and etzi — with these, you can handle almost any daily conversation about dates.
Datorren (coming)
To talk about “next week” or “next month,” you use datorren + noun:
Basque
English
datorren astean
next week
datorren astelehenean
next Monday
datorren hilean
next month
datorren urtean
next year
Datorren means “that comes” or “coming” (it’s the relative form of the verb etorri, to come). The important thing is to learn it as a block.
”This” — hau / honetan
For “this week,” “this weekend”:
aste honetan — this week
asteburu honetan — this weekend
hilabete honetan — this month
Other key markers
Basque
English
orain
now
gero
later, after
lehen
before
gaur goizean
this morning
gaur arratsaldean
this afternoon
gaur gauean
tonight
bihar goizean
tomorrow morning
Goiza = morning (part of the day). Bihar = tomorrow (the next day). They are two different words, don’t mix them up!
Asking questions about time
Noiz? — When?
Noiz etorriko zara? — When will you come?
Noiz egingo dugu afaria? — When will we make dinner?
Examples in context
Bihar mendira joango naiz. — Tomorrow I will go to the mountain.
Etzi euskara klasea dut. — The day after tomorrow I have Basque class.
Datorren astean lan asko izango dut. — Next week I will have a lot of work.
Asteburu honetan ez dut planik. — This weekend I don’t have any plans.
Cultural note: in Basque, “morning” as a time of day is goiza, and “tomorrow” as the next day is bihar. The phrase bihar goizean (“tomorrow morning”) combines both. It’s very common to get this nuance wrong in early conversations, so it’s a good idea to get it straight from the beginning.
